The Voice coach Will.i.am has branded the final result of the show and "unexplainable" - adding that he was "perplexed" by the public vote.
Former Oasis frontman Liam Gallagher has been booked as an unlikely guest on BBC1 talent show The Voice.
Holly Willoughby is stepping down from her role as co-host of talent show The Voice to concentrate on her family, the BBC has announced.
The mother-of-two will be replaced by Emma Willis, who has just finished a stint of presenting Celebrity Big Brother.
Reggie Yates, Willoughby's co-presenter, is also leaving the BBC One singing contest, with his replacement set to be announced next week.
The This Morning presenter said: "After much consideration, I will not be returning for series three of The Voice UK.
"I've had two wonderful years on the show, and I feel very privileged to have been a part of it. Finding the right balance between my work and family life is my priority and this has contributed to my decision."
Kylie Minogue has been named as a new coach on The Voice for the BBC show's upcoming series.
Kylie will join returning coaches will.i.am and Sir Tom Jones on the famous red chairs - two of which were left empty by singer Jessie J and The Script's Danny O'Donoghue.
The singer said she was "very excited", adding, "Will I be competitive? Probably more than even I imagine! Watch this space!"
A fourth coach has yet to be announced.
Singer Jessie J has left her role as a coach on The Voice after two series of the show.
The 25-year-old cited overseas touring and promotional commitments as the key factors in her departure.
The singer said: "I've absolutely loved my time on The Voice and I hope everyone saw and knows how passionately I felt about the show.
"However, I can't wait to promote my new record around the world and that has to take priority."
"I shall be keeping a very close eye on series three, showing my support in every way I can, and really hope that in some way that I can be part of the show."
It is yet to be confirmed whether fellow coaches - Sir Tom Jones, Danny O'Donoghue and Will.i.am - will be rejoining the panel for the third series.
Last month partially sighted Andrea Begley beat hot favourite Leah McFall to be voted the winner of the second series - a decision which left coach Will.i.am left "perplexed".
Phillip Schofield has leapt to the defence of This Morning co-host Holly Willoughby following the furore over her "unsuitable" choice of dress for the final of The Voice.
The BBC apologised to viewers after more than 100 complaints were made after the presenter wore a low-cut black lace maxi dress for the final which was broadcast before the watershed.
Schofield took to Twitter to mock the decision:
"139 complaints over Holly's gorgeous Voice dress. Let's hope those outraged on behalf of their kids don't take them to the beach this summer...God forbid they might see a woman in a bikini before 9pm and be traumatised by the sight of her cleavage."
In a statement a BBC spokesman said the corporation was sorry if some viewers found the dress "unsuitable".
"Holly enjoys fashion and we felt the dress she wore for the live final of The Voice UK was glamorous and wholly appropriate for the occasion.
"We don't believe it would have gone against audience expectations for a TV spectacle such as this."
Andrea Begley, 27, from County Tyrone was voted the winner of BBC's The Voice tonight, landing a major record deal as her prize.
Speaking on her victoru Andrea Begley said she "never, ever, ever could have imagined" was possible.
The partially-sighted singer from County Tyrone in Northern Ireland, who has just 10% vision, was rendered tongue-tied when her name was announced as the winner of the BBC show.
"I actually can't speak," she said.
Adding: "I never ever ever could have imagined this."Andrea, described as an "inspiration" by her coach Danny O'Donoghue from The Script, promised fans she would do her utmost to build on her win.
"Hopefully I'll try my best to put your vote to good use and be a success," she said.
Speaking to the radio times, the Welsh pop legend said: "I feel like I know what I am doing this time and it feels more natural.
"Last year we were given suggested lines just in case we got stuck, which I tried to work in on a few occasions."
The crooner said the comments were not him, and made him feel self-conscious.
Sir Tom returns with fellow coaches Jessie J, Will.i.am, and Danny O'Donoghue for the second series of the show this weekend.
Jessie J, Sir Tom Jones, Danny O'Donoghue and Will.i.am will be competing against each other on the BBC talent show, which is set to have some new twists this time round.
The show's ratings dropped during the first series following the end of the "swivel chair" rounds.
An 11-date tour featuring performances from the finalists was cancelled, due to poor ticket sales.
Leanne Mitchell, who was mentored by Sir Tom won the show last year, but a download version of her debut single failed to make it big in the charts.
