Cheryl Cole is set to return to 'The X Factor'.

The Girls Aloud star - who quit the ITV1 show last year to become a judge on the US version, before being sacked after just a few episodes - has had talks with the programme's boss, Simon Cowell, about coming back to the judging panel as he thinks she's the only person who can help dwindling ratings.

A source said: "Cheryl is coming back on TV in 2013 and will be working with Simon. People love to watch her. She was with 'X Factor' at its peak."

Her friend and manager will.i.am confirmed her return, saying: "It's going to be dope."

Cheryl's return means current judge Tulisa will be axed and Gary Barlow is also set to leave.

Simon wants Nicole Scherzinger - whose act James Arthur won last night's (09.12.12) final - to stay and isn't sure about the future of Louis Walsh.

The source added to the Daily Mirror newspaper: "There are going to be the biggest changes ever on the show. We gave to respond to the drop in ratings and level of interest."

Other changes will see the start of next year's show being moved back to the weekend after children return to school to make it the most talked about by young fans.

Saturday shows will start earlier and the arena auditions will be axed in favour of hopefuls singing in a small room in front of just the judges.
