Oprah Winfrey is releasing a new book.
The media mogul will publish a collection of essays, entitled 'What I Know For Sure', which will be compiled from the monthly piece she has published in O, the Oprah Winfrey Magazine for the last 14 years on September 2.
The essays will be grouped in the book by theme, with topics covered including gratitude, joy, awe and possibility, and the tome will "offer a rare, powerful and intimate glimpse into Oprah's inner life - her thoughts, struggles and dreams - while providing readers a guide to becoming their best selves."
Meanwhile, Oprah - who has previously published two weight loss manuals and a behind-the-scenes guide to the making of 1998 movie 'Beloved' - has paid tribute to her best friend Gayle King.
The 60-year-old talk show host has been close to her pal for almost 40 years after they bonded over bad weather which led to Oprah lending Gayle some underwear.
She is quoted by the New York Post newspaper as saying: "I want to say officially how proud I am of my friend Gayle King.
"Back a lifetime ago, 1976, Baltimore. We were both on a local TV station. She was a production assistant. I was an anchor. We became friends, especially after a big snow storm. When she couldn't go out, get home and didn't have enough clothes, I said, 'OK, you can have my underwear.' But then I added, 'And don't return it.'
"When time came and things happened to me, I asked her to quit her job and come to my new Oprah magazine to help me. But the truth is, the whole time I felt guilty taking her away from TV because I know how much she loved it.
"And now she's doing so well, and I'm thrilled for her. Mostly because at least she can have her own underwear."

Miley Cyrus' giant tongue "badly injured" a crew worker, a lawsuit claims.
Charles Nicholas Sarris has filed a claim against ShowFx Inc., the Los Angeles-based equipment supply company which was hired to make the novelty mouth slide for the 'Wrecking Ball' star's 'Bangerz' tour, in which he claims he suffered an accident while working on the construction of the prop.
According to gossip website TMZ, Mr. Sarris says the equipment and tools provided to him by the company failed, causing him to fall and badly hurt himself last month.
In the lawsuit, he claims ShowFX failed to warn him about the potential dangers and is suing for unspecified damages.
Earlier this week, Miley was forced to perform her track '23' in her underwear after missing her costume change during a gig.
She tweeted: "not a new outfit for 23 I didn't make my quick change and I couldn't not come out for the song so I just had to run out in my undies 🙁
"Never happened to me before. But I love my fans as much as they love me! I couldn't miss 23
"Show must go on 🙁 (sic)"
Miley kicked off her raunchy world tour in Vancouver, Canada, last month and came under fire for antics such as simulating a sex act on a man wearing a Bill Clinton mask, but she insists she gave fans a pre-warning her shows would be X-rated.
She previously wrote on Twitter: "You can't say I didn't warn you. Now sit back relax & enjoy the show. #bangerztour (sic)"

Ashley Roberts says The Pussycat Dolls will be getting back together.
The 32-year-old star and her former group mates have all gone their separate ways since splitting in 2010, but she claims they will "definitely" be reuniting to bring back their hits such as 'Don't Cha' and 'When I Grow Up'.
When asked if there were plans for a reunion, she said: "I don't know, I really don't. Never say never, but I know at the moment we're all on our own paths right now.
"Definitely someday. Not quite yet. It will happen when it's supposed to."
Ashley - who competed on the ITV reality show 'I'm A Celebrity ... Get Me Out Of Here' in 2012 and has since gone on to judge on 'Dancing on Ice' - claims that although the rest of the dolls, Nicole Scherzinger, Kimberly Wyatt, Jessica Sutta, Carmit Bachar and Melody Thornton are busy with their own projects at the moment, she's keen to get back to working on music.
She told OK! Magazine: "I'm a music baby, that's the heart and sole of me. I'm going back to my roots."

Tina Fey has denied reports that there will be a 'Mean Girls' reunion movie.
The 43-year-old comedienne - who wrote the original film - has shot down rumours that there could be a sequel after it's star, Lindsay Lohan, last week revealed she'd been approached by Fey and added that there could be a 10th anniversary project in the works.
Fey told Access Hollywood: "[There's] definitely not a movie. It's just the anniversary is coming up, so everybody get your pink shirts. It's been 10 years. You can tell when you look at me it's been 10 years."
The former 'Saturday Night Live' star didn't completely rule out any kind of reunion for the cast - which included Lindsay, Rachel Adams, Amanda Seyfried and Lacey Chabert - but said there definitely isn't going to be a follow up to the catty high-school comedy.
She explained: "I said to her [Lindsay], 'Oh, I think someone may call us about doing some kind of reunion because next month is the tenth anniversary of the movie.' And so really... if everyone's around we might try to do some kind of like panel discussion.
"But it's not like - it's not another movie. At most it would be like a panel discussion with a plate of hot wings."

Charlie Condou says Marcus Dent and Maria Connor's split was "inevitable".
The actor has been at the centre of a sordid love triangle in 'Coronation Street' of late, cheating on his girlfriend - played by Samia Ghadie - with Todd Grimshaw (Bruno Langley), and he admits he foresaw a messy split for Marcus and Maria.
Charlie exclusively told BANG Showbiz at the TRIC Awards in London: "He loves her very much, but this is soap - it's never gonna end well! When they told me about the storyline of Marcus and Maria getting together, I knew it would end in tears at some point. It was inevitable."
Things will go from bad to worse next week when scheming Todd arranges for Maria to walk in on him and Marcus in the middle of a tryst, but Charlie has defended his alter-ego and insists Marcus can sense he is being used by Todd.
He said: "I think he's not stupid, Marcus ... he's already getting a sense that he's being played, and I think that comes out quite quickly. Todd knew that Maria was coming, but Marcus is very attracted to Todd and there's a lot of chemistry there, he can't keep away from him.
"It's head and heart in a lot of ways ... I think he's trying to fight off the inevitable. There's going to be a lot of heartache coming in the next few weeks."

Roger Lloyd-Pack was originally scripted into the new 'Only Fools and Horses' sketch.
The late Trigger actor - who passed away in January following a battle with pancreatic cancer - had expressed his desire to star in the charity special with Sir David Jason, Nicholas Lyndhurst and football legend David Beckham before his untimely passing.
The new sketch was written by Jim and Dan Sullivan, the sons of show creator John Sullivan, who passed away in 2011.
Jim said: "It has been emotional, and dad was never far from our thoughts during the whole process.
"And, of course, we were all shocked and saddened at the news of Roger Lloyd Pack's death. We had originally written Trigger into the sketch and Roger was supportive of the whole thing.
"We had heard he had been unwell but had no idea how serious it was. It wasn't until shortly before filming that we heard he was too poorly to perform, such was eagerness to be involved - a true testament to his character."
The Sport Relief sketch was conceived when David, 38, approached the brothers about doing a charity special and the duo were taken aback by what a big fan the retired football player is of the sitcom.
Jim told Radio Times magazine: "We had no idea and it was lovely to meet him and hear him talk about his favourite episodes and scenes, and how his son, Brooklyn, is now also a fan."

Joan Collins has recreated Ellen DeGeneres' Oscars 'selfie'.
The 80-year-old actress gathered a group of British celebrities, including Sir Ben Kingsley and Jeremy Irons, together at the Prince's Trust and Samsung Celebrate Success Awards in London yesterday (12.03.14) to recreate the famous snapshot, taken by Bradley Cooper on the talk-show host's phone at the Oscars ceremony earlier this month.
The 'Dynasty' actress managed to encourage a number of the other guests at the awards to get involved and the result was a rather blurry photograph of Joan, Ben and Jeremy joined by Pixie Lott, Vernon Kay, Jools Holland, Dominic West and Luke Evans.
Meanwhile Vernon Kay's wife Tess Daly, sports broadcaster Gabby Logan, 'X Factor' winner Sam Bailey and presenter Phillip Schofield missed out on being involved in the British version as Joan's arms couldn't stretch as far as the 'American Hustle' stars did.
Posing together at the 86th Academy Awards at the Dolby Theater in Los Angeles for the original 'selfie' were Ellen, - who was hosting the ceremony - Bradley, Julia Roberts, Jennifer Lawrence, Meryl Streep, Brad Pitt, Angelina Jolie, Kevin Spacey, Channing Tatum, '12 Years a Slave 'star Lupita Nyong'o and Jared Leto, who was unfortunately squeezed out of the shot.
Joan has since posted her "selfie support" on Twitter in a bid to receive more retweets than Ellen's image - which broke records with over 3.2 million people retweeting the star studded photo - but so far it's only been re-posted by under three hundred social-media users.

Rihanna and Drake were spotted holding hands after his concert in Manchester on Tuesday night (11.03.14).
The 'What Now' singer, 26, and the 24-year-old rapper are rumoured to have gotten back together and they now appear to have confirmed their relationship after they were seen holding hands as they made their way to the after-party at Club Entourage.
Following the party the couple are said to have continued their night out together by renting out an entire bowling alley where they stayed until four o'clock the next morning, according to TMZ.com.
This isn't the pair's first date since reportedly rekindling their romance however, as they were also seen getting hot and steamy at London's celebrity hotspot Cirque Le Soir on Monday night (10.03.14) and appeared to have enjoyed a romantic meal together on Sunday (09.03.14) as they were photographed leaving the Nobu restaurant in Mayfair.
Speaking about the music stars' night at Cirque Le Soir, a source said: "There's definitely no question about their romance anymore. Rihanna and Drake spent the whole night with their tongues down each other's throats and didn't seem to care about everybody seeing."

Karen Gillan found it "scary" when she first saw herself as Guardians of the Galaxy's Nebula.
The 26-year-old actress - who shaved her head for the part - will play the female villain in Marvel's big-budget superhero film, where she dons purple face paint and a black face-piece.
Gillan could believe what she was seeing when she saw herself in the mirror, dressed in character, for the first time.
Talking to collider.com: "I couldn't believe it. I was like 'woah'. I'd seen mock up pictures and they'd done make-up tests on other people, so I had an idea. But, when I saw it on myself it was really scary."
The make-up and costume helped Gillan get into character since she didn't feel like she was herself.
She added: "It did half the job for me. I mean, having shaved my head and working out so much, I just felt like a different person so that really helped with the performance."
She will star alongside Chris Pratt who will play the lead role of Peter Quill - otherwise known as the Star-Lord.

Skrillex wanted his debut album to be "crazy".
The dubstep producer, real name Sonny Moore, kept details of his record 'Recess' a secret before streaming it in full on his Alien Ride app on Tuesday night (11.02.13) ahead of the official release on March 18.
Skrillex told Rolling Stone magazine the process was about: "Taking my sound and expanding on it, but being more playful, taking it to different places."
The record features a number of cameos, including Chance the Rapper, Diplo and Kid Harpoon and Skrillex insists he has worked hard to make the album cohesive.
He explained: "I call my songs vibescapes ... There's always a foundation under the tracks that you can feel and pick up on. An emotion. There's a lot of organic samples ... wind, breaths, clocks cut into tiny pieces.
"I never made pure club music early on. All the first Skrillex releases were hard to mix into."
He added: "I wanted to make a crazy record [but] I wanted to stay true to who Skrillex is."
Talking about the mysterious app, which was nothing more than a game with a countdown clock, Tim Smith, his longtime manager, said: "That signals that something's coming, but no one knows what it is."
Skrillex, 26, admits he'll probably make less money sreaming his album through the app first but it was "more about the fans."

Neil Patrick Harris "loves being scared".
The 'How I Met Your Mother' actor enjoys being frightened and taking part in daring stunts and thinks that's why he always enjoyed hosting the Tony awards.
The 40-year-old star said: "I love being scared, walking through a field of maize in October with people jumping out and frightening me.
"I know they can't touch me and I like the experience of it -- weirdly, I think hosting the Tony Awards is almost the same thing. I'm out there, it's live, something could go terribly wrong, but we have lots of outs and I have a teleprompter and we've already rehearsed everything. It's fun and a bit dangerous, but I know I'm going to be all right."
The actor, who hosted the ceremony four times before passing on the baton to actor Hugh Jackman this year, is baffled by stars who can't read an autocue.
He told OUT magazine: "It always amazes me when Oscar-nominated actors go on award shows and read the teleprompter as if they have never seen it before.
"And I know they've already vetted it, that their publicist or manager has already agreed to it, and yet, there they are, standing there, with that kind of 'Who wrote this s**t?' attitude while monotonically reading off these words."
The star, who will appear as womaniser Barney Stinson in 'How I Met Your Mother' for the last time this month as the Fox show comes to an end, is sad he's leaving the character behind but looking forward to new challenges.
He said: "I won't ever be able to play someone like Barney again because he's so unique, but we had over 200 episodes ... And my exclusivity deal is done with Fox."
He jokingly added: "So finally I'll be able to do more porn."

Dominic Cooper hates fancy dress parties.
The 'Need for Speed' actor favours casual clothes when he isn't working and hates socialising at parties where he has to dress up as a character because it reminds him too much of his work.
He said: "I love anything vintage, a good quality suit, scruffy jeans and my trusty leather army boots. I like being casual. As an actor, I'm in costume all the time. That's why fancy dress parties are my idea of hell."
The 35-year-old star is an avid follower of fashion and takes a particular interest in emerging designers.
He said: "I can't believe how easily fads come back into style, like skinny jeans. But I've always loved fashion.
"It influences generations and resonates with a moment in time. I love seeing what designers come up with, especially young designers. I think they're artists."
And Dominic can also remember splashing out on his first-ever new suit to mark his appearance in stage show 'The History Boys'.
He told Britain's InStyle magazine: "When I got paid for doing 'The History Boys' in New York, I bought a nice suit. No idea who by, but it was a big moment as, before that, I'd only worn hand-me-downs with baggy kneecaps. I certainly didn't have the money to buy suits when I was a teenager."
