Cheryl Cole has ruled out a return to The X Factor after declaring it part of her “past”.

The singer suggested she was bored with speculation about whether she would go back to the ITV1 show and said it is time to “move on”.

It follows comments earlier this week by talent show judge Louis Walsh who reportedly said she “could be back”.

Cole left the UK show to join the panel for Simon Cowell's US version when it launched last year, but she was axed amid claims that her Geordie accent was difficult to understand.

Cole posted a message on Twitter which said: “X Factor was a great experience and time in my life and career but is now part of my past. Please let's move on now. Zzzzz *yawns*.”
