The BBC One reality series, which launches tomorrow, will see the panel members being only allowed to listen to act, and can only judge on their voice whether or not to put them on their teams.
Speaking to TV Buzz magazine this week, Will.i.am confessed he's been having some trouble deciding whether or not to push his buzzer.
“I’m really p***** off with myself for not turning around for the last act ,” he explains. “I hesitated when I should’ve just used my imagination – she was out-of-the-box and I’m an out-of-the-ordinary type of artist. I didn’t live up to what I’m here for by not picking her.”
Tom Jones on the other hand has been suffering the opposite problem.
“I was told that I was being a bit trigger-happy,” he confesses. “I had to be reminded that I could only pick ten people from all of the blind auditions – and I’d chosen five on the first day!”
The Voice UK starts on BBC One at 7PM this weekend.
