The 29-year-old singer is currently working on both the Girls Aloud comeback and promoting her own album - and is claimed to be resisting efforts to get her back on the show.
A friend of the star told The Sun: "Cheryl really enjoyed her time on the show but she has moved on. She had three really good years and wants to leave it there."
And her spokesperson added: "Cheryl has no plans to return."
Bosses on the show are reported to have offered Chezza the head judge role on the UK version of the show if she returns.
She made the headlines at the weekend after turning up to a gig in a sideboob-showing playsuit.
