Jay Z has turned down the chance to be Kanye West's best man.
The 44-year-old rapper only agreed to the idea initially providing his family - including wife Beyonce and their two-year-old daughter Blue Ivy - wouldn't be filmed for Kim Kardashian's reality show.
Speaking to the Daily Star newspaper, an insider revealed: "Jay is Kanye's closest friend so he wants him to be best man.
"Jay agreed initially but had one condition - under no circumstances can there be any reality TV shows filming him, his wife, Beyonce or daughter Blue Ivy during the ceremony."
Meanwhile, Jay Z's wife is also said to be totally against appearing on 'Keeping Up With The Kardashians'.
The source added: "The thought of popping up in 'KUWTK' mortifies Beyonce.
"She purposefully keeps herself away from trashy TV and isn't prepared to lower her standards for anyone, or any occasion."
However, E! bosses - who run Kim Kardashian's reality show - are reportedly "desperate" to air the ceremony, meaning Jay Z may miss out on being best man.
The insider said: "Bosses at E! are desperate to get the nuptials on air, and will pay millions to make it happen."

Blake Fielder-Civil's mother "made excuses" for his and Amy Winehouse's drug use.
The late singer's former mum-in-law Georgette Civil has admitted she defended the 'Back To Black' hitmaker and her son, become his "enabler".
Speaking about first meeting Amy, she explained to The Sun newspaper: "Amy looked glowing. She threw her arms around me and said, 'Isn't our boy handsome?' I adored her.
"But later, we all sat at dinner and Amy kept ducking under the table. Then Blake said, 'You'd better go to the bathroom', and she went upstairs. [My second husband Giles] turned to Blake and bluntly asked him, 'Are you doing drugs?', but I reacted furiously, saying, 'Of course he isn't'.
"From that moment, I became Blake's enabler - making excuses for him and Amy."
Indeed, Georgette revealed she "wasn't strong enough" to accept Blake's cry for help, despite the singer - who died of accidental alcohol poisoning in July 2011 - inviting her for a meeting at a hotel.
She said: "One day, Amy invited me to another hotel where she and Blake were staying. He sat at the table and said, 'Mum, I have a dependence and need help. There's been times I've spent £600 a day on heroin.
"I took him in my arms and said, 'You are talking nonsense'. I t was his only cry for help - but I wasn't strong enough to face the truth ... It was only later that I suddenly realised that Blake was a hopeless addict.
"But by then, I was caught up the lies and deceit myself - and it was too late to save Amy."

Dannii Minogue says Cheryl Cole will thrive as the only female judge on 'The X Factor'.
The pair were on the panel together in 2008, and the fashion star has backed the former Girls Aloud singer to be a huge success if she does decide to return to the TV talent show.
She told The Sun newspaper: "I don't know what's going on with the panel but if Cheryl does come back as the only girl I don't think she'll miss female company too much.
"I liked the fashion wars but Cheryl will have more than enough glamour and frocks to do it on her own.
"And she can definitely hold her own with just the boys. I think she'll love it."
It has been said that Cheryl told show bosses she wants to "be the only woman" judging on the show, and as negotiations continue she "seems to be calling the shots".
An insider recently said: "If Cheryl does come back as planned, she will be the only woman on the panel. That's how she wanted it and at this moment she seems to be calling the shots.
"They're still finalising the other details but Cheryl made it clear she didn't want to be pitched against another female again."

'Sherlock' creator Mark Gatiss says Benedict Cumberbatch is irreplaceable.
The show's boss admitted the programme would not be able to continue without its leading man in the role of the fictional detective, and insisted both he and Martin Freeman are vital to its success.
Speaking to the Daily Mirror newspaper, he said: "If Benedict went under a bus tomorrow it would be the end of the show.
"Benedict and Martin are our stars. We do three episodes a year and although people want more that's all we can do. They are so famous now it's difficult to get them."
Mark recently responded to criticism at fans having to wait until 2016 for new episodes - due to their two lead actors having very busy schedules - and point out the gap between series is "always" a similar length.
He explained: "Everyone wants to carry on doing 'Sherlock'. It's a simple matter of schedules - particularly Benedict and Martin.
"They've become superstars, which is brilliant, but we all want to carry on as long as we can.
"There was suddenly a kind of outraged response that it might not be back until 2016 but that's precisely how long it always is. It's always two years! But we'd like to return soon, of course."

Paloma Faith feels like a "competition winner" because of her high-profile collaborators.
The 'Can't Rely On You' singer has worked with a string of famous faces on her new album 'The Perfect Contradiction' and can't believe stars like Pharrell Williams and Raphael Saadiq wanted to write with her.
She said: "On this album I didn't approach hardly any of the people, I met Pharrell at the Met Ball [last year] and came up and asked to work with me, which I was gobsmacked about. He came up to me and was like, 'I think you're so cool' and was singing my songs to me. I was just like, 'How do you even know who I am?'
"Raphael I met because I was opening for Prince and he was as well, he was like 'Let's write together.'
" I feel like a competition winner."
Paloma admits she found it hard to concentrate when she entered the studio with Pharrell because she was so in awe of his youthful good looks.
Asked what it was like entering the studio with him, she said: " Difficult to concentrate because he's so beautiful and I can't believe he's 43, he looks about 15. And his wife is devastatingly beautiful. He's nice and humble."
Though they got on well, the 32-year-old singer admits she hasn't heard much from the 'Happy' hitmaker recently.
She joked in a radio interview: " I've got his phone number and email. He's quite busy now, he doesn't reply as much as he used to. I think I'm left out on the doorstep."

Cameron Diaz spent days with Jason Segel's "package in her face" making 'Sex Tape'.
The pair star in the comedy series about a couple who video themselves recreating the Karma Sutra - a famous ancient Indian sex manual - only for it to go missing, and filming the initial scenes required a certain level of intimacy between the co-stars.
Cameron told People magazine: "[We] got to know each other very well. Our day was, 'My butt is going to be in your face, your package is going to be in my face."
Despite the raunchy subject matter, the health conscious star says the shoot was one of the most fun she's been on.
She added: "[It was the] funniest job I've ever had. It was highly athletic. Jason and I had to keep our strength up."
The 'Bad Teacher' star has recently written 'The Body Book' and through learning about her body she recently urged women to take better care of their private parts and treat their genitals like "beautiful flowers".
She said: "We think the vagina is on the outside. I say grab a mirror and play along. Get in there.
"Learn about it. You're supposed to treat it like the beautiful flower that is, the delicate flower that it is. And you're supposed to nurture it in all the ways that it needs nurturing. Watering it. Fertilising it. It needs nourishment. It's hungry."

Lena Headey used to fight a lot.
The actress was well-equipped for her role as Spartan Queen Gorgo in '300: Rise of an Empire' because she has plenty of experience of scrapping when she was younger, though she is unsure why she came to blows so often.
She said: "I did a lot of training, which I love. I'm a tomboy. I used to get into a lot of fights. Don't know why, self-expression I guess. I got into boxing."
The 40-year-old actress has a three-year-old son, Wylie, from her marriage to
musician Peter Loughran and she enjoyed bringing the little boy to the set of the movie because he was impressed by her sword-fighting skills.
She added in an interview with People magazine: "He was on set during a fight scene. He stood up and said, 'Ninjas, be gentle!"
Lena - who also plays Queen Cersei in 'Games of Thrones' - also finds it funny how she's picked for regal roles because she isn't like that in real life.
She said: "I'm covered [in tattoos]. That's what's hilarious. You couldn't get less royal than me."

Sir Paul McCartney had a special dish made for him at a restaurant in Hollywood.
The vegetarian 'Please Please Me' singer and his wife, Nancy Shevell, ate with his former The Beatles bandmate Ringo Starr and his spouse, Barbara Bach, at upmarket eatery Il Piccolino, but when he couldn't decide what he wanted from the menu, the owner took him to speak to the chef and they came up with an appetising dish.
A source said: "The owner, a friend, escorted the ex-Beatle into the kitchen where Paul - who loves to cook - watched intently as the chef prepared veggies chosen by the star."
The star was then thrilled when he even got a special extra treat with his dinner - the recipe written out just for him.
The source added to National Enquirer magazine: "Paul went back to his table and was thrilled when his repast arrived, complete with the chef's handwritten recipe."
Paul has previously spoken of how much he enjoys the "creative" vegetarian food options available in restaurants.
He said: "Even 20 years ago, it could sometimes be difficult to find vegetarian options in good restaurants. Now it's great to see more and more choice with some brilliant creative dishes in restaurants, cafés and supermarkets. There is definitely now an overall greater acceptance of being vegetarian."

Channing Tatum and Jenna Dewan Tatum "communicate" differently now they are parents.
The 'Step Up' co-stars are parents to Everly, nine months, and the actress says having a daughter has brought her closer to her husband because they have so many more decisions to make.
Jenna said: "You become closer because you have to be in the same page to make decisions for the baby.
"It makes us communicate about things we never did before."
Channing and Jenna adore their baby, but also recognise its important for them to spend quality time as a couple, so they organise regular date nights.
She told Us Weekly magazine: "You have to have adult conversations for your own sanity. So we get a sitter, go out and have some fun. We're very good about making time for that."
Jenna also says the youngster is very much daddy's girl.
She has said: "He's like a big kid. He plays with her, and she laughs harder and smiles bigger than she does with anyone. Dad comes around and it's playtime. She's like, 'Mom, I'll talk to you later!'"

Phillip Schofield thinks it's the "best time" for 'Dancing on Ice' to end.
The 51-year-old presenter - who fronts the ITV show with Christine Bleakley - is sad to see the skating competition end after nine years this weekend, but is glad to end on a high.
He told new! magazine: "I'm enormously proud of the programme - it's a beautifully made show - but it's the best time to go, while it's still on top. I've really enjoyed presenting it so much."
Phillip says the standard of competition on the final all-stars series of 'Dancing on Ice' is higher than ever and he can't quite predict who will win on Sunday (09.03.14).
He explained: "They're all brilliant but Ray Quinn is getting better and better. Hayley Tamaddon has been great and Beth Tweddle is a very talented skater. They are all turning in great routines. But let's not forget, it's a public vote."
The silver-haired fox also shared his favourite moment from 'Dancing on Ice', admitting he couldn't contain his laughter when former 'EastEnders' actor Todd Carty faced some technical difficulty in 2009.
He recalled: "One of the funniest times was when Todd Carty disappeared out of the rink. We all loved that. And the quality of skating in this final series has been extraordinary."

Sue Perkins initially turned down 'The Great British Bake Off'.
The 44-year-old TV presenter - who fronts the BBC Two baking competition with Mel Giedroyc - has admitted she passed on the chance to host the show at first because she didn't think it would last.
She said: "They said, "Would you do it?' and I said, 'No, it's about cakes, don't be silly.' "
However, Sue is now thankful she changed her mind as 'Bake Off' has enjoyed momentous success over the past four years and will soon move to BBC One.
She added: "I can't tell you how joyous it is. I'm the luckiest person alive."
The comedienne's role in the show has led to worldwide attention and she is recognised where she least expects it.
Appearing on 'The Jonathan Ross Show' - which airs on ITV tomorrow (08.03.14) - Sue said: "I was in Angkor Wat, the massive temple in Cambodia, doing a really pretentious piece to camera - that thank god will never make the edit - and a load of guys went, 'Bake.' "
Sue and Mel have become good friends with judge Mary Berry, 78, and recently introduced the sophisticated TV chef to tabloid talk show 'The Jeremy Kyle Show', which features scandalous revelations and family feuds.
She revealed: "Mary loves Jeremy Kyle. We've got her into Jeremy Kyle. She says, 'This is extraordinary. Absolutely marvellous.' Then after a while you go, 'It is real.' [Mary says] 'Is it really?' "

Shia LaBeouf didn't actually have sex with his co-star in 'Nymphomaniac'.
Actress Stacy Martin knows scenes between her and Shia are particularly intimate in the movie - about a self confessed sex addict recounting her life story - but they were achieved through careful use of prosthetics and porn doubles.
She told Nylon magazine: "Neither Shia nor I were willing to actually have sex onscreen, obviously.
"Everything was set in place for us to have a porn double, a prosthetic vagina, special effects.
"As actors, we could be ourselves and commit to an amazing project, but we were protected as human beings, and, speaking for myself, as a woman."
Stacy, 22, also said the script led to her and Shia to have some very interesting conversations off-set.
She added: "We'd be sitting around in restaurants, saying, 'You know the penis scene? How are we going to do that?' "
The budding actress has previously said filming some of the sex scenes got a little boring because they were so technical.
She said: "It's not the most relaxing experience. It is quite strange, but also it is very, very technical. It almost becomes a bit boring because [director] Lars [Von Trier] gives you a lot of freedom when you're filming in general, and then suddenly you are restricted into doing certain positions and being very specific. Because they have to match everything together [with the doubles], you just have to really obey what they tell you. So you just have to get on with it."
