Sharon Osbourne is reportedly being lined up to return to the 'X Factor' judging panel in 2013.
Osbourne quit the show in 2008 but now sources close to her have allegedly said she is ready to make a comeback.
It's thought the reality star would replace Tulisa on the judging panel. The source said: "Tulisa is over it, she has had enough of the politics on the show and doesn't want to go back.
"She is getting worried about how she is perceived on the show and thinks it would be better to quit while she is ahead to carry on with her music."
Former N-Dubz star Tulisa's debut album 'The Female Boss' has been panned by critics and only just poked its way into the top 40.
Tulisa originally recorded new single 'Scream & Shout', which was then charmingly called 'I Don't Give a F**k', after co-writing it with Will's pal Jean Baptiste, and she had included it on some early versions of her album.
But after it was dropped from the record, Will enlisted the help of Britney to re-record a new version - which is now headed for number two in the UK charts.
