Will.i.am is set to quit 'The Voice'.
The Black Eyed Peas star - who has spent three years on the show - has reportedly decided to leave to focus on his own music career, following the departure of fellow coach Kylie Minogue.
An insider told the Daily Star Sunday newspaper: "Kylie quitting is a huge blow but the knock-on effect is going to be ten times worse.
"Will wants to concentrate on his own music and with Kylie not coming back he's told producers he won't either.
"The fear is that [Sir Tom Jones] and [Ricky Wilson] will follow suit.
The TV talent show has already been commissioned for two more series, but bosses are concerned about the possibility of having to find an entirely new quartet for the judging panel.
It is said Justin Timberlake is being discussed as a potential replacement, due to the 'Mirrors' hitmaker's talent and credibility.
The insider added: "Justin Timberlake's name has been put forward as the perfect replacement for Will and Kylie.
"He's a huge star, which would give the show credibility and he's still relevant, which would bring in the viewers."

David Walliams had to apologise after wrestling Simon Cowell on 'Britain's Got Talent'.
The former 'Little Britain' star tackled his boss during an audition after the 54-year-old star tried to stop an act the rest of the panel wanted to continue, and he was told he had crossed a line.
David told The Sun on Sunday newspaper: "Simon is quite a serious person and he doesn't want me dragging him down to my level, as I learned at one point when we had a wrestle.
"There were a couple called Que Sera, who sang 'Love Changes Everything', and he said, 'Oh I hate this song'. But we all wanted to hear it.
"So he tried to put is hand in the air to stop the song and we ended up wrestling. He said, 'I'm a serious music mogul, people can't see me wrestling on TV.' "
It turns out this isn't the first time David has been given a dressing-down from Simon, who was less than impressed when his co-star hit him with a pen he threw during one of the shows.
He added: "He had a word with me too over pen-gate - when I lobbed a pen at him during one show. It turns out that I'm a better aim than I thought - and I hit him.
"The thing is you are trying to be outrageous and funny, and you are going to fail some of the time. You see it over the years that comedians do get it wrong.
"So I had to say sorry to him about the whole thing. He just said to me afterwards, 'David, David that was too much', and I said, 'I'm very sorry. I'm sorry.' "

Lorde doesn't mind being called arrogant.
The 'Royals' singer can sometimes come across as aloof, but claims it's a deliberate move and says she aspires to be as confident as her idol Kanye West.
She admitted: "I like making grand statements. The name Lorde is quite grand and a little bit arrogant. I like that, I like the intensity of it."
Probed about some critics calling her arrogant, she replied: "I don't mind. I'm a really big fan of Kanye West. He's confident and I like that. I'm not that confident in myself yet."
Despite her image, the 17-year-old pop sensation is actually a shy person and found it tough fitting in with her famous peers at first.
She explained in an interview with France's NRJ radio station: "I am shy and I'm pretty private. I'm getting way better at being in those situations. It's still really weird for me.
"I've learnt to have fun. I've made a lot of friends as well in this industry so I don't feel like such an outsider."
One person Lorde has become particularly close to is 23-year-old star Taylor Swift, but although they are good pals, the Kiwi singer doesn't think they will ever collaborate musically.
Quizzed whether they were going to record a duet, Lorde burst into giggles and replied: "I don't think so, no. She's great though."

Peaches Geldof's ashes will be scattered alongside her mother's.
The late 25-year-old star will be laid to rest in the grounds of the gardens of Davington Priory, Kent - where her childhood home stood - as it held a special place in her heart following Paula Yates' own funeral at the nearby St. Mary Magdalene church.
A source told the Sunday Mirror newspaper: "Peaches' happiest memories were there - there would have been no other place to hold the funeral and have her ashes scattered. The family were all so happy there - it was just idyllic."
The decision was reportedly made after discussions between her husband Thomas Cohen, father Sir Bob Geldof and sisters Fifa, 31, Pixie, 24 and 17-year-old Tiger.
Peaches' old nanny Anita Debney was also involved in the talks, and she recently paid tribute to the late star on Instagram.
She wrote: "She has been the greatest joy, the greatest blessing, the most tender part of my heart and soul. I loved her through the good times and the bad. We struggled and survived the darkest of times.
"I never lost faith in her spirit and strength. Always held out my hand to help her when she struggled and fell. She overcame so much and my love and appreciation of her indomitable spirit never wavered."

The 28-year-old singer was devastated by her tragic miscarriage in November 2010, and has opened up about the "horrendous" complications which left her fighting for her own life.
She told The Sun on Sunday newspaper: "It was horrendous and something I would not wish on my worst enemy. It's something that I still haven't dealt with ... But it's not something that you get over.
"I held my child and it was really horrific and painful - one of the hardest things that can happen to a person ... I nearly died. But I was numb and I didn't care. I'd just lost my baby and that is a reflection of how numb I was."
The 'Air Balloon' hitmaker and her husband Sam Cooper went on to have daughters Ethel, two, and Marnie, one, and they still feel their son is part of the family.
She explained: "I just think that he's a part of my eldest really. If he hadn't died, it wouldn't have physically been possible for our eldest to be alive because I got pregnant with her so quickly.
"We've gt a little stone in our garden with his name on. And lots of different things that I do, rituals, I have him in my mind."

Snoop Dogg has been getting close to Playboy bunny Carla Howe.
The married rapper is reportedly seeing a lot of the British model, who has previously dated the likes of will.i.am, and isn't trying to hide their meetings from wife Shante Broadus.
Speaking to The Sun on Sunday newspaper, an insider said: "She has become smitten with him.
"They've started to spend a lot of time together - she even accompanied him to his birthday party because his wife didn't attend ... Snoop doesn't hide anything.
"He's posted a video on Vine of Carla and her twin. He's also allowed her to post pictures of them together on her Facebook and Instagram accounts."
The 'Drop It Like It's Hot' himaker married his wife in 1997 - although he filed for divorce divorced in 2004 before remarrying four years but it is said Carla's feelings for the star are becoming more intense.

Anastacia sings about the pain of divorce in her new album.
The 'Left Outside Alone' hitmaker filed for divorced from Wayne Newton 2010 and she used the emotions she felt during that tough period in her life to help shape tracks on her forthcoming record 'Resurrection'.
She said: "I had done a lot of healing on that score prior to writing the album. But there are definitely things in there that attest to the strength, mourning and the pain of divorce - the ebbs and flows. I had such a plethora of unwritten emotions in my heart that once i opened the floodgates it all came pouring out.
"The songs do paint a picture of resurrection - someone who is stripped. I know I've stripped myself of a lot to try and find what's inside."
Anastacia - who was first diagnosed with breast cancer in 2003 and last year she revealed she had a double mastectomy after the disease returned - also wrote her new album in the wake of her second cancer diagnosis, and two of the songs explore her determination to beat the disease.
She added in an interview with Britain's HELLO! magazine: "['Stay'] is pretty much a song that says I'm not ready to go just yet - not ready to die. As I was writing it, I knew it was intense. Then I came home and played it for my sister and she cried.
"But at the same time its got this playful energy - it's almost kind of childlike in the music."

Wally Pfister is "privileged" to have Johnny Depp star in his first feature film.
The cinematographer-turned-director - who has previously worked on Christopher Nolan's films including 'The Dark Knight' trilogy - says it's a big vote of confidence to have top actors such as Depp and Morgan Freeman sign up to star in sci-fi thriller 'Transcendence'.
He said: "I was very privileged on my very first film to have that kind of talent. They made the experience both comforting and artistically fulfilling.
"Johnny loved the script when he read it. I think he thought he could do something fun and interesting with the character. There were a lot of conversations together to decide what we wanted to do and how we wanted him on screen."
In 'Transcendence', Johnny plays Will Caster, a scientist who works to create an artificial intelligence (AI) that is smarter than any living human. But his work is disrupted when an anti-technology terrorist group attempts to assassinate him and sabotage his research.
Wally was determined to ground the film in real science and had the script properly vetted by researchers.
He added in an interview with SFX magazine: "'Transcendence' is a contemporary film and all the science has been vetted by university professors. I spoke to professors at MIT, Stanford, Berkeley and Caltech about everything from neuroscience and neurobiology to nanotechnology and artificial intelligence."

Kim Kardashian has allegedly been sleeping in a corset to try and lose weight.
The 'Keeping Up With The Kardashians' star has been preparing for her upcoming nuptials to Kanye West, which are reportedly set to take place at a secret Paris location next month, by trying out a number of natural beauty treatments and weight-loss methods while on holiday in Thailand with her family.
A source told Grazia magazine: "Kim wants he figure to look absolutely perfect on her wedding day. Wearing a corset at night is extremely uncomfortable but has a proven record of results, and with six weeks to go, Kim is up for anything."
The brunette beauty - who gave birth to her and Kanye's first child, North, last summer - also underwent the ancient procedure of "butt, face and breast slapping" which reportedly costs £200 for a 15-minute session and erases wrinkles, shrinks pores and tightens skin.
The source added: "Kim did a lot of reading into these natural techniques online before her trip, and she had three 15-minute treatments of each while she was there."

Keira Knightley says she can't have a personal life while working on films.
The 'Anna Karenina' actress' schedule so extremely busy when she's on set that she doesn't ever have the time to catch up with her close friends because of her "extreme" lifestyle.
She said: "When I'm not working it's really about seeing as many friends as possible and making sure I'm there in their lives. The way I work is extreme. You can't really have a personal life if you're working on films all the time. There's Skype, but, really, there's just no way of doing it.
"The hours are so long, you're always in a different country, you're always doing a different thing."
Keira, who married Klaxons vocalist and keyboardist James Righton last year, enjoys catching up with her pals when she has time off in between movies.
She added in an interview with Red magazine: "It becomes very important to block out some time when I don't work and that's how I retain friendships, otherwise people just float. You kind of become somebody who is rudderless."

Taylor Momsen has quit acting forever.
The Pretty Reckless singer rose to fame aged 14 as Jenny Humphrey in the CW's hit teen drama 'Gossip Girl', only to leave the show for good after the fourth season, declaring she was taking a break from Hollywood.
And Taylor - who started out alongside Jim Carey in 'The Grinch' as a child - is adamant she won't ever be tempted to return to the big screen because music is her true passion.
Quizzed on France's Virgin Radio station whether she would consider a film role, she categorically said: "No. Just music. I'm not pursuing it at all. I haven't acted in five years. It feels like a past life."
The star is best known for her controversial music videos, her rock 'n' roll attitude and grunge-inspired style these days, and insists she is just as hardcore as she seems.
Talking about her tipple of choice before opening for Guns N' Roses, the 'Just Tonight' hitmaker quipped: "Have a whiskey and walk on stage. [Fruit juice] is not an option."
The 20-year-old singer also hinted she would be open to the possibility of meshing her rock sound with rap in the future.
Taylor explained: "It would have to be the right fit. But there's a South African rap group called Die Antwoord I'm a big fan of."
