Sam Callahan thinks Robbie Williams would make a "better" 'X Factor' judge than Gary Barlow.
The former contestant - who received weekly criticism from Gary over his mediocre performances in last year's competition - would have preferred his Take That bandmate be part of the show instead.
Sam explained to BANG Showbiz: "Robbie Williams would be pretty cool, he'd be pretty good. I mean he's the opposite to Gary. He's a real showman and entertainer.
"Robbie's been an idol of mine since I was little, he's an absolute entertainer. It's not like watching anyone else. As a judge I think he would be better for me."
Sam even offered some career advice to Gary - who announced he was leaving the show during last year's competition - believing he would be better suited as a judge on rival BBC show 'The Voice'.
Speaking at the launch of charity event We Day earlier this week, he said: "I think Gary would be good on 'The Voice' because it's about the vocals, because that's what he's always banging on about. But 'The X Factor' is about having the X factor - the full package, and that's what I went there to do."
He added: "At one point he gave me some criticism that was just literally, you know, negative. When you moan at me for one thing you have to think about the whole thing."
We Day, and educational programme We Act, is coming to the UK on March 7, 2014.
