The 31-year-old presenter has decided to step down as a judge on the talent show after just one series on the panel alongside Simon Cowell, Rita Ora and Cheryl Fernandez-Versini but is still a "massive fan" of the programme.

His spokesperson said: "After careful consideration, Nick's decided to rule himself out as a judge on this year's 'X Factor'.

"He loved working on last year's series alongside Rita, Cheryl and Simon but it was very much a once-in-a-lifetime experience. He remains a massive fan of the show and is looking forward to watching it this year."

Insiders claim Nick stepped down before show boss Simon had chance to axe him.

The source told The Sun newspaper: "Nick made the decision to jump before he was pushed and that is completely understandable."

Meanwhile, Caroline Flack is not expected to return as co-host of the show.

The 36-year-old star faced criticism for her presenting partnership with Olly Murs, but is also in negotiations to star in a West End production of 'Chicago' so would be unable to do both.

A source said: "Caroline's a really experienced broadcaster but the combination of two presenters just didn't work out this year.

"It's unfortunate for her, but the decision gives her the opportunity to take on a major West End role, which is something she's wanted for a long time."

Simon is keen to keep Cheryl on the panel, while Rita and Olly's fates are not yet known.

However, the music mogul reportedly already has One Direction hunk Louis Tomlinson in line to replace Nick, though will also consider a return for Louis Walsh.

A show source said: "Louis Tomlinson is very likely to replace Grimmy. He agreed in principle to the job while assisting Simon Cowell during the judges' houses round last year.

"But Simon remains very fond of Louis Walsh and came very close to bringing him back during last year's live shows.

"He felt a certain something was missing on the show without him."
