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".
Cheryl left the UK show to join the panel for Simon Cowell's US version of The X Factor when it launched last year, but she was axed just two weeks after auditions started, amid claims that her Geordie accent was difficult to understand.
Responding to Louis' comments, Cheryl 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."
She added: "Please let's move on now. Zzzzz *yawns*"
Music manager Louis reportedly told the Daily Mirror: "I'll tell you who the panel will be. It will be Gary Barlow, Louis Walsh, Tulisa and perhaps Cheryl Cole. She could be back. I'm not saying she definitely will but I'd love to see her."
