The BBC Radio 1 DJ is rumoured to be taking a place on the ITV show's judging panel but the Take That star - who sat on the panel for two years between 2011 and 2013 - has expressed reservations that Nick will be able to commit to the talent competition and his role as presenter for the Radio 1 Breakfast Show.

Gary told the Daily Mirror newspaper: "I'll tell you what. It's a lot of work, it's half the year gone, that's without any other job so he needs to weigh that one up.

"He's a character, that's the point."

Meanwhile, Louis Walsh - who is quitting as a judge of the show after over a decade - has revealed the show's boss Simon Cowell is "seriously" considering having Nick take a place on the panel.

Louis said previously: "I think Simon's got Grimmy in mind, definitely. It's something he's talked about seriously - he's thinking three boys and Cheryl [Fernandez-Versini] on the panel."

Although the official judging panel has yet to be announced, Louis has insisted Simon will continue with four judges.

He added: "Simon wants it to work - he's brilliant, he's a perfectionist. Viewers want arguments between the judges, they want passionate people. Even this is all just a game - every year, who is gonna get the job and who isn't?"
