'Coronation Street's' Carla Barlow will discover she's pregnant next week.
The Weatherfield character's husband Peter Barlow (Peter Gascoyne) - who has been having an affair with Tina McIntyre (Michelle Keegan) - will be forced to re-evaluate his recent antics when his wife drops a baby bombshell.
A soap source said: "Life is going to throw the Barlows a curveball! It's the last thing that either of them expected and it'll stir up many complex emotions - mostly, what on earth is Carla going to do with the baby?"
Peter will be torn between his two lovers, but it's not yet known whether he will give up his affair now Carla (Alison King) is pregnant.
The source told Inside Soap magazine: "That's a good question but you'd have hoped he wouldn't do the dirty on Carla full stop - pregnant or not!
"We know that Peter genuinely adores Carla and she is his soulmate. His feelings for her have never wavered, he's just got a lot of love to give and Tina's been tempting him.
"Let's hope he can see the error of his ways before another innocent victim is dragged into all of this."

Ollie Locke feels like he has been through a "break-up" since leaving the 'Celebrity Big Brother' house.
The former 'Made In Chelsea' hunk, who flirted with 'The Only Way Is Essex' beauty Sam Faiers during the recent series, claims he misses seeing her every day and and finds the situation strange.
When asked about their possible relationship, he said: "The honest answer is that I feel like I've gone through a break-up.
"That's what it feels like. I've just spent almost 30 days with someone that I really like and suddenly I'm not with her anymore. It's a bit bizarre."
The 27-year-old star flirted up a storm with Sam, 23, during his 26-day stint on the reality show, during which he admitted he had feelings for the pretty blonde, which he says he doesn't regret.
He said: "I'm used to having my relationships on camera. But it is different with this one. We both said that if anything were to happen it would be when we were on the outside.
"But nothing's happened yet but we do speak every day."
Ollie says it "really annoys" him that some viewers thought their flirting was a 'showmance' for the cameras and he insists they do really like each other.
He added to heat magazine: "If it was, why didn't we properly get it on inside the house for everyone to see? In my eyes - and I think hers, too - if something was going to happen then it would be now we're out of the house. But we still need to talk about that."

Conor Maynard loves meeting up with his famous friends at the BRIT Awards.
The 21-year-old singer was a guest at the annual ceremony on Wednesday night (19.02.14) - the fourth time he has attended - and likes the fact he gets to mingle with other musicians when he's there.
He told BANG Showbiz: "I think one of the best things is getting to see a lot of artists you haven't seen in a while. It's like a catch-up ... I share a label with Tinie Tempah and he's a really cool guy, so we hang out. It's also good for meeting new people and meeting new artists you haven't seen before. It's very exciting."
When asked if had cleared his schedule for Thursday (20.02.14) to cope with his post-BRITs hangover, Conor laughed: "That's always a good idea, I better check what I'm doing!"
Although he loves going to awards shows, Conor always feels nervous when host James Corden starts asking the audience impromptu questions.
The 'R U Crazy' singer - who performed at the Brooklyn Bowl in New York as part of BRITs Week at The O2 on Tuesday night (18.02.14) - said: "It's quite nerve-wracking, especially with James Corden presenting it, you never know what's going to happen. He could come over to you and ask you some random question and put you on the spot! It could be a career-ending moment!"

Kendall and Kylie Jenner are to release their novel in June.
The reality TV stars have turned into budding authors after penning thrilling young adult book 'Rebels: City of Indra', which is based on two young girls Lex and Livia, who embark on a journey together, but later realise their biggest danger might be each other.
Kendall, 18, told E! News: "Kylie and I love the creative challenge and are thrilled to have been given the opportunity to share this story."
Kylie, 16, added: "We can't wait to share these characters and the world we created with readers everywhere. We are so excited!"
The brunette beauties have teamed up with writer Maya Sloan for the novel, which is "set 200 years in the future", for publisher Karen Hunter at Simon & Schuster.
However, the youngsters - who have their own clothing line - have held back some of their creative ideas as they want to write a series based on Lex and Livia.
Kendall said: "We want to do something so different, something that we really love."
Meanwhile, Kendall and Kylie's half-sister Kim Kardashian also has her heart set on becoming an author and is already working on a saucy book, which appears to be loosely based on experiences from her own life in the limelight.
'Rebel: City of Indra' is set for release on June 3.

Lorde thinks Prince is "a big deal".
The 17-year-old singer triumphed at the BRIT Awards last night (19.02.14) after being crowd the Best International Female, and she admits she was frozen on the spot when the 'Purple Rain' hitmaker and his new band 3RDEYEGIRL walked past her backstage.
Speaking exclusively to BANG Showbiz, she said : "Prince walked past me in the corridor that was the craziest moment ever, sheer surprise, he's a big deal."
The 'Royals' hitmaker fought off stiff competition from Katy Perry, Lady Gaga, Pink and Janelle Monae, but she insists she never expected to win being up against some of the best women in music.
She explained: "I feel super good. I really didn't expect to win at all. You don't expect to win an award when you're up against like Gaga and Katy Perry. I'm really grateful and stoked!"
Meanwhile, the brunette beauty also took to the stage at London's O2 Arena during last night's ceremony to do a performance with Disclosure.
She said: "The BRITs got in contact and said, 'Would you be up for performing with Disclosure'. I was like, 'Yes!', very keen. I love those boys I think they're so talented and I love working with young people. I met them a few days a go."

Simon Cowell has taken his newborn son to a business meeting.
The 54-year-old star took Eric - who was born last Friday (14.02.14) - and his girlfriend Lauren Silverman to meet with some executives from TV channels in New York City after he failed to cancel his plans.
A source told The Sun newspaper: "Baby Eric came along two weeks early so Simon still had meetings he was going to attend.
"As the birth went relatively smoothly, he decided to keep the appointments and asked Lauren to bring him along to him show off."
The 'X Factor' boss is expected to start his paternity leave next week, but friends close to him believe there will be nothing coming between him and a potential big project.
A pal said: "He's a workaholic. He lives for it. He loves Eric to bits but if an exciting idea comes up, he will want to be all over it like a rash."
Meanwhile, Simon - who plans to divide his time between London and New York - has applied for his son's first passport as he wants to take Eric back to the UK to introduce him to his mother Julie.
However, it is thought that Eric won't board a transatlantic flight for a few more weeks as experts recommend waiting until a newborn is four to six weeks old before taking them on an aeroplane.
Simon previously revealed he and Lauren - who has eight-year-old son Adam with her ex-husband Andrew Silverman - were planning to move over to the UK on a permanent basis.

Johnny Marr insists The Smiths would have only signed to Factory Records over his "dead body".
The guitarist claims rumours they were refused a deal by Tony Wilson's famous label in the 1980s were a "crock of sh*t" and the band preferred being signed to London's Rough Trade.
He told the NME: "If you were a musician in Manchester at that time, it was almost the law that you went on your hands and knees and begged Tony Wilson for his papal blessing to stick you in the studio, and I wasn't about to do that.
"So much has been made of Factory apparently turning The Smiths down, but that's a crock of sh*t.
"The Smiths would have signed to Factory over my dead body ... I didn't want to be assimilated into the Factory aesthetic. Before we knew it, we would've had side-partings and khaki shorts, with bongos round our necks ... No disrespect to A Certain Ratio."
The musician also said The Smiths - including Morrissey, Andy Rourke and Mike Joyce - looked like a band "all the f***ing time" and their jeans were specially manufactured by their manager, Joe Moss.
Johnny, 50, said: "Literally no-one else on the planet had those jeans. Mine had little V's in the side, as a tribute to the Perry Boys and Stuart Sutcliffe.
"Morrissey had his made with the big baggy seams at the back, so they were almost falling off him.
"But we didn't have to dress up for Top Of The Pops, because we lived offstage what we lived onstage."

'Sex and the City' has "one story" left to tell, admits filmmaker Michael Patrick King.
The 59-year-old director insists the story of Carrie Bradshaw and her girlfriends Samantha Jones, Charlotte York and Miranda Hobbes - played by Sarah Jessica Parker, Kim Cattrall, Kristin Davis and Cynthia Nixon respectively - isn't over, but remained cryptic about whether he would helm a sequel to 2010's 'Sex and the City 2'.
He told Entertainment Weekly: "The great gift or riches or luck is that I worked on two shows that were so full that they spilled over into people's lives and the characters were rounded enough that you could still wonder where they are.
"Sarah Jessica and I both know what that final chapter is. That doesn't mean it will or should be told, but I do think there's one story left. Whether it ever happens is a whole other situation. But there's four girls, and those girls are still in my mind. There are other stories to tell and characters that haven't even been written yet."
This comes after Parker revealed she isn't ready to throw away her Manolo Blahniks just yet and would happily reprise her role as style icon Bradshaw on the big screen - as long as the sequel happened in the near future.
She previously confessed: "A part of me thinks there is one last chapter to tell. But timing is a peculiar thing. It isn't a decision that can wait forever. I don't want to have to wear muumuus [a loose dress that hangs from the shoulders]!"

Alexandra Burke wants to be an actress.
The 25-year-old singer - who shot to fame after winning 'The X Factor' UK in 2008 - has been trying her hand at different things over the past two years to diversify her career but she's now decided to take up theatre classes in a bid to become a Hollywood starlet.
She said: "It's been challenging. It's something that I wouldn't say comes naturally to me. In school, I loved doing singing, dancing and acting. It came naturally to me at 16, I just need to get back on to it so it can be natural again."
The 'Let It Go' hitmaker has already picked her dream leading man to star opposite, 'Mandela: A Long Walk to Freedom' star Idris Elba.
Alexandra has a crush on the 41-year-old actor and dreams of being his co-star.
When asked what her dream role is, she told the Belfast Telegraph newspaper: "Anything that's next to Idris Elba because I love him! He's such a talented young man."

Matt LeBlanc is a "little more together" than his on-screen persona.
The 46-year-old actor plays a fictional version of himself in 'Episodes' but admits he is noting like his character in real life.
The former 'Friends' star told Boston Common magazine: "It's a fictitious character, and you just have to approach it that way. He just happens to have the same name I do. When we were coming up with who the character was going to be, I thought it would be fun - since our salaries were all published during 'Friends' - to make this Matt LeBlanc way, way wealthier than me.
"You've got this guy completely oblivious to the consequences of his actions; that's fun to play. And he's really damaged, this lost soul, the Matt LeBlanc on TV."
But he added: "I like to think I have my s**t a little more together than that."
Matt, who has a 10-year-old daughter Marina with his ex-wife Mellissa McKnight, is glad he has regained some anonymity since 'Friends' came to an end in 2004.
Recalling his time on the show, he said: "The weirdest thing was walking into a room, a restaurant, a bar, a movie theatre, anywhere there's a lot of people, and everybody sort of stopping what they're doing and taking notice you're in the room. And they know you, or they think they do - they know your name, they know what you do for a living, they know how much money you make, they know where you're from, but they're all strangers to you."

Katie Holmes tries to be proactive about her health for the sake of her daughter.
The 35-year-old actress, who secured sole custody of Suri Cruise, seven, following her divorce from Tom Cruise in July 2012, is determined "to be there" to watch her daughter grow up.
The brunette beauty, who is teaming up with US department store Kohl's to encourage more women to join the fight against breast cancer, told PEOPLE.com: "I've known a lot of people who have been diagnosed and women tend to take care of everyone else before our own needs. Becoming a parent made me much more aware of my own health. I want to be there for my child for a long time."
The former 'Dawson's Creek' star also opened up about her love of living in New York City and how Manhattan has been "very good" to her and Suri.
She said: "I love the community in New York. I love New Yorkers. I ran into someone on the street the other day that I went to high school with. I love the moments of spontaneity every day."
She added: "New York has been very good to both of us. I love the theatre, the galleries in my neighbourhood. Stuff [like] that is so much of what makes me love this city. I love the Knicks. I love talking to my neighbours in the elevator. I like feeling a part of something big."

Simon Cowell has applied for his newborn son's passport.
'The X Factor' boss, who plans to divide his time between London and New York City, where his girlfriend Lauren Silverman's eight-year-old son, Adam, lives, accompanied the brunette beauty to a courthouse in Manhattan on Wednesday (19.02.14) to file papers to get a passport for their baby boy Eric, who was born on Friday (14.02.14).
A source told gossip website TMZ.com that both parents were required to be present to file the official government paperwork and Simon is only in the city for a few days.
The 54-year-old star plans to introduce his child to his mother Julie in the UK for the first time, but it is thought that Eric won't board a transatlantic flight for a few more weeks as experts recommend waiting until a newborn is four to six weeks old before taking a baby on an airplane.
Simon previously revealed that he and Lauren, 36, were planning to move back to London soon after Eric's birth, as the star will be working on his ITV series.
Earlier this month, he said: "Lauren knows what my work schedule is so she is cool with that and we will travel a little bit.
"We made the decision to come back to the UK and she wants to live here for a while."
