Sir Paul McCartney was set up with Nancy Shevell by Barbara Walters.
The 'Hey Jude' legend married the trucking company boss in 2011 after four years of dating, and 'The View' host reportedly takes the credit for getting them together at one of her parties.
A source said: "Barbara was so determined to make it work that she'd call Nancy and coach her on Paul's likes and dislikes. Barbara was quite right - they were ideal for each other. Barbara was right, they were ideal for each other. Now Paul calls Nancy his soul mate."
Nancy also has the approval of his grown up children - Mary, Stella and James, with first wife, Linda - which is something his second wife, Heather Mills, with whom he has Beatrice, 10, never achieved.
The source added to National Enquirer magazine: "When Nancy became Lady McCartney in October 2011 she wore one of his daughter Stella's designs. That's something Stella didn't want Heather to do.
"And of course, front and centre at the simple London wedding was Barbara, taking credit for making the perfect match."

will.i.am watches CBeebies.
'The Voice' star has revealed he loves watching children's programming first thing in the morning before he starts his day.
He said: "In the morning I watch CBeebies - that's what I like to wake up to. Is that weird?"
The Black Eyed Peas star splits his time between London, where he films 'The Voice', his home in Los Angeles, and most recently, Australia, where he has signed up as a coach on their version of 'The Voice' with Kylie Minogue.
Quizzed about what he gets up to when in London, will said: "I used to always be in the studio when I was here, but now I go to clubs and eat out with friends. I enjoy seeing Kylie Minogue, but we're with each other so much now that we're both on 'The Voice' Australia as well, we appreciate the time apart."
Starring on two versions of 'The Voice' isn't a chore for the star, however, as he enjoys working with young, talented musicians.
He added to Radio Times magazine: "I do 'The Voice' because I enjoy being around people who have dreams, and I have a record label and produce, so it's healthy for us to nurture tomorrow's artists."

Charlie Sheen and Denise Richards will enter private mediation next week in a bid to resolve their child support issues.
The 'Anger Management' star, who has two daughters Sam, 10, and Lola, eight, with his ex-wife, wants his monthly $55,000 child support payment to Denise, 43, reduced and for her to be evicted from one of his houses.
A source told gossip website RadarOnline.com that the actor's lawyers have "formally notified Denise and her lawyers that they will be headed to private mediation next week to try and get the child support reduced.
"The mediation will be handled by a retired judge who has handled various issues for the former couple over the years since their divorce. It looks like this will go down early next week. Wednesday by the latest."
But the source added: "Charlie could be taking a huge gamble by taking Denise to the mediator. There is a chance that the judge could actually increase the child support to Denise because of his lucrative 'Anger Management' deal with FX. This could be a can of worms Charlie might wish he never opened."
Charlie, 48, and Denise were previously close friends but fell out in December, after he blasted her for not inviting him to spend Christmas with her and their daughters.
He allegedly wants his child support reduced because he claims he isn't allowed to spend anytime with the girls, even though Denise has sole custody.

Fergie is a huge fan of Jessica Alba's organic company.
The Black Eyed Peas singer, who has a seven-month-old son Axl Jack with her husband Josh Duhamel, regularly buys baby products from the 'Fantastic Four' star's eco-friendly brand, The Honest Company, because they don't contain any toxic materials.
The 38-year-old star told People.com that she now has "a whole bag" of must-haves from her friend's line, and said: "I feel like [she's] done a great job with that company."
Fergie added: "She sent me some [diapers] when he was born and I wrote her a thank you. But I've ordered more since she sent them to me because they're great. I love her moisturising cream as well."
The 'Pump It' hitmaker is very proud that her little boy is currently learning to sit up by himself but admits he has also developed a soft spot for her famous blonde locks.
She said: "He likes to grab on to everything -- including my hair, which I completely encouraged in the beginning. I loved when he touched it, he got so happy. I felt this bond with him as a mommy. I think that a lot of feelings that you have as a mom, they're so pure and loving. But I asked for it, so now he grabs it all the time!"

Austin Mahone insists that Selena Gomez is a "real sweet" girl.
The 'MmmYeah' hitmaker has voiced his support for the 'Come & Get It' singer, who has recently attracted criticism for reuniting with her on/off boyfriend Justin Bieber, following her brief stint in rehab in January to "clear her head."
Asked if he had spoken to the brunette beauty, whom he was previously rumoured to have romanced, the 17-year-old star exclusively told BANG Showbiz: "Not recently."
But he added: "She's real cool, she's real sweet, real nice. We're friends and she's always there for me too."
The duo were introduced to each other through their mutual friend Taylor Swift and were last spotted together at the Beats Music concert in Los Angeles in January, shortly after Selena left her treatment facility.
Sources previously indicated that many of the 'Spring Breakers' star's are unhappy that she had reunited with Justin, whose bad behaviour has escalated in recent months and is facing a number of legal troubles.
Meanwhile, Austin sparked speculation this week that he has moved on with Fifth Harmony member Camila Cabello, 17, as he posted a number of glowing tweets about her band on Twitter, but they have only hung out "once or twice."
He said: "I would say me and Camila are good friends. I've hung out with her once or twice, so we're good friends."
But he added: "I just think she's really cute, I think she's funny and sensitive. She's a cool girl."
The heartthrob is set to guest star on an upcoming episode of 'The Millers' next week and wants to pursue more acting roles in the future because he really enjoyed filming the show.
He said: "I had a good time. It was pretty cool. I'm interested in going back again and I'm definitely interested in any opportunity in acting that I get."
Austin will appear on 'The Millers' on Comedy Central next Wednesday (26.03.14) at 9.30pm.

Idina Menzel thinks she "only benefited" from John Travolta messing up her name at the Oscars.
The 'Pulp Fiction' actor was met with ridicule on social media after accidentally calling the 'Frozen' actress "Adele Dazeem" when he introduced her to the stage to perform 'Let It Go' at the event earlier this month, but she insists the pair have since become "buddies."
The 42-year-old star told Billboard.com: "He was really gracious and sent this gorgeous email, and we're buddies and it's all cool."
She added: "Please. I mean, I've only benefited from it!"
John also sent the actress a huge bouquet of flowers to apologise.
Idina, who was previously married to Taye Diggs, was initially a little flustered after hearing the star's introduction.
She said: "That threw me for a minute. But then I just got back on track and reminded myself of where I was, and what a beautiful moment it was."
While Travolta's flub pulled some of the attention away, Menzel gave a show-stopping performance of 'Let It Go', which was crowned Best Original Song at the Academy Awards, beating Pharrell Williams' 'Happy' - from the 'Despicable Me 2' soundtrack - and U2's 'Ordinary Love', which is featured in 'Mandela: Long Walk to Freedom'.
'Frozen' also took home the prize for Best Animated Feature, despite stiff competition from 'Despicable Me 2' and 'The Croods'.
The family-friendly flick - which features the voices of Menzel, Kristen Bell, Josh Gad and Jonathan Groff - is on course to become Disney's highest grossing animated film and a stage adaptation is in the works.

Sarah Michelle Gellar has urged her fans to boycott US Vogue.
The former 'Buffy' star announced she is cancelling her own subscription, hinting she disapproves of fashion editor Anna Wintour's decision to put reality TV star Kim Kardashian and Kanye West on the cover of magazine's April issue.
The 36-year-old actress wrote on Twitter: "Well......I guess I'm cancelling my Vogue subscription. Who is with me???"
Many of the blonde beauty's followers agreed with her, but Kim's best friend Jonathan Cheban was unimpressed by her comment.
He retweeted the message, adding: "Do u matter? (sic)"
Kim and her rapper fiancé's front cover caused shockwaves when it was unveiled on Friday (21.03.14), as Anna was previously said to have declared the 'Keeping Up with the Kardashians' star, 33, would only appear in the magazine "over her dead body."
And it appears the fashion icon predicted a backlash, as she defended her decision to feature the couple in her monthly editor's letter, insisting Kanye, 36, didn't have to "beg" her for the opportunity.
Meanwhile, sources told E! News that 21-year-old model Kate Upton, who first appeared on the front of the magazine last year, was dropped as the April cover star in favour of Kim.
But Hildy Kuryk, Communications Director at Vogue, insisted: "We are all huge supporters of Kate here at Vogue and have been thrilled to feature her numerous times in the past year, both on the cover and inside the magazine. There was never a cover commitment made to Kate, and we look forward to working with her in the future."

Anna Wintour thinks Kim Kardashian has "real guts."
The US Vogue editor, who previously had a frosty relationship with the reality TV star despite being close friends with her fiancée Kanye West, claims she decided to put the 'Keeping Up with the Kardashians' beauty on the cover of the magazine's April edition because she admires Kim's "strength of character."
In her editor's letter for Vogue's Shape issue, the cover of which features the 'New Slaves' hitmaker with his arms around Kim, who is wearing a strapless Lanvin wedding dress, the fashion icon, 64, writes: "There's barely a strand of the modern media that the Kardashian Wests haven't been able to master, and for good reason.
"Kanye is an amazing performer and cultural provocateur, while Kim, through her strength of character, has created a place for herself in the glare of the world's spotlight, and it takes real guts to do that."
She said that the magazine has a tradition of "being able to feature those who define the culture at any given moment, who stir things up, whose presence in the world shapes the way it looks and influences the way we see it."
She joked added: "I think we can all agree on the fact that that role is currently being played by Kim and Kanye to a T. (Or perhaps that should be to a K?)."
Kim and Kanye also posed for photographs with their nine-month-old daughter North West for the first time in the magazine, and a source told People.com that everyone was impressed by the E! star.
The insider said: "Annie and Grace Coddington [Vogue Creative Director] we're so impressed with how professional Kim was. They all laughed throughout the shoot and had so much fun.
"Kim tried tons of wedding gowns made for her by every designer."
Another source added: "Kim is so grateful and loved shooting this with Kanye and North."

Chris Brown has vowed to turn his life around.
The 'Fine China' singer, who was transferred to a jail in Los Angeles after he was kicked out of a court-ordered rehab facility last Friday (14.03.14), and must stay there until his next probation violation hearing on April 23, has told friends he is absolutely miserable behind bars.
A source, who recently spoke to the 24-year-old star, told gossip website TMZ.com that Chris said being in prison is "the worst experience of my life," and he feels like "a caged animal."
He also reportedly said: "I'll never f**k up again."
The 'Don't Wake Me Up' singer has been spending his time in jail writing new music and working out.
But Chris could be out of jail early next week, as his lawyer is close to reaching a civil settlement with a man the star allegedly assaulted in Washington D.C.
The Grammy-Award winner's representative Mark Geragos is said to have offered Parker Adams, who claims Chris broke his nose and hurled a homophobic slur at him last October, a large financial deal in the hopes of convincing him to tell prosecutors he no longer wants to participate in the criminal case against the star.
Chris, who was first placed on probation in 2009 after assaulting his then-girlfriend Rihanna, is facing a misdemeanour assault charge in relation to the incident and could be sentenced to four years in jail if convicted.

Blake Lively is glad she took some time off to enjoy being a newlywed with Ryan Reynolds.
The former 'Gossip Girl' star tied the knot with the actor, 37, in a secret ceremony near Charleston, South Carolina, in September 2012, and admits it was "really nice" to take a break from the spotlight for most of last year to focus on their relationship.
The 26-year-old actress told the April issue of Elle magazine: "Having a personal life has been really nice. I'd been on Gossip Girl 10 months a year for six years, shooting 15-hour days, so I hadn't had time to just be since I graduated from high school."
She added: "It's been nice to kind of settle into my own skin and work on things I really love."
But the blonde beauty is now ready to reignite her career and is currently filming 'The Age of Adaline' in her husband's native Vancouver, Canada.
A source told E! News that Blake has been working very hard on the movie and pulling all-nighters this week.
The movie, which also stars Harrison Ford, is set to be released next year.

Alyssa Milano is expecting her second child.
The 41-year-old actress, who recently admitted she and her husband David Bugliari were "actively trying" to give their two-year-old son Milo a sibling, has revealed she is pregnant again.
The 'Mistresses' star announced the happy news on her blog on Friday (21.03.14), writing: "We are so happy to share with you that Milo is going to be a big brother!"
She also shared a link to the post on Twitter, writing: "Ahem! Click here for some BIG, HUGE, HAPPY news."
Last month the brunette beauty joked that her husband, who is a Hollywood agent, was even taking supplements in a bid to increase her chances of getting pregnant.
She said: "We are actively trying. David's] just chugging down ginseng [a herbal remedy believed to increase sex drive and improve erectile function in men]."
Alyssa - who shot to fame on 'Who's the Boss' when she was 11 years old - was forced to defend her post baby body after being insulted by 'Suburgatory' star Jay Mohr during a radio interview in December.
He said: "It seems like she had a baby and said, 'I don't really give a s**t'.... I read it on her gut."
Alyssa challenged him on Twitter after hearing the rude remarks but eventually accepted his apology.

Kim Kardashian says securing the front cover of US Vogue is "a dream come true."
The 'Keeping Up with the Kardashians' beauty was snapped by famed photographer Annie Leibovitz for the magazine's April issue with her rapper fiancé Kanye West, after he reportedly spent more than a year trying to convince its editor Anna Wintour to like the reality TV star.
Clearly ecstatic, the 33-year-old star shared an image of the cover on Twitter, which shows her wearing a strapless white wedding dress with Kanye standing behind her with his arms wrapped around her waist, a nod to their upcoming wedding in Paris on May 24, shortly after it was released on the magazine's website on Friday (21.03.14).
She tweeted: "This is such a dream come true!!! Thank you @VogueMagazine for this cover! O M GGGGGG!!! I can't even breath! (sic)"
Her mother Kris Jenner also shared the image and tweeted: "Gorgeous!!!! @voguemagazine kimkardashian @kanyewest #amazing #stunning #soproudofyoutwo #AnnieLeibowitz (sic)"
A source first revealed in March 2013 that Kanye was on a mission to get Kim on the cover of Vogue despite Anna allegedly branding Kim as "the worst thing since socks and sandals."
The insider also claimed that the style icon said Kim would only appear in the esteemed magazine "over her dead body".
Kim and Anna's feud has been well documented in the past.
The 'Keeping Up With The Kardashians' star was banned from attending the star-studded Met Gala in New York in 2012 because Anna believed she "didn't fit the bill," and she was only invited to the annual event last year because Kanye was performing.
A source said at the time: "Anna hates Kim. Why would she be invited to the event? It is all the biggest stars in the world and Kim doesn't fit that bill at all. The Met Gala is $25,000 a ticket, but Kim couldn't even buy her way in."
The fashion editor also allegedly ignored Kim at New York Fashion Week in September 2012, but she recently sat beside Kim's half-sister Kendall Jenner at Topshop's runway show at London Fashion Week suggesting the famous family had finally won her over.
