The BBC has reportedly had to alter plans for The Voice UK's grand final after big names such as Adele and Justin Bieber declined to appear.
According to the Daily Star, producers wanted to follow the show's usual format by booking big names to duet with the finalists, with the 'Someone Like You' and 'Baby' singers on their wishlist alongside Kelly Clarkson and Flo Rida.
But the top four - Bo Bruce, Leanne Mitchell, Tyler James and Vince Kidd - will now be teamed up with their coaches after all four stars turned down the offer.
Bookies' favourite Bo is apparently 'gutted' that Adele won't be appearing. The 27-year-old was quoted as saying: "I really wanted to sing with her."
However, a BBC spokesperson rubbished the claims, saying: "The Voice format has been adapted for UK audiences. We never planned to have other artist duets for the final."
Maroon 5 - whose frontman Adam Levine is a coach on the American version - and Ed Sheeran have already been confirmed for guest performances on the final, which begins on Saturday at 7.00pm on BBC One.
