X factor judge Louis, 56, thinks the Girls Aloud star, 25, will become a full-time TV presenter and revealed: "Cheryl is stealing the show this year."
And as the Westlife and Boyzone manager revealed to notw.co.uk last month, he has backed the tough-talking Geordie to emulate scouse legend Cilla Black.
Louis said: "Simon says he thinks Cheryl could become the new Cilla Black. I think she'll do a couple more years in music, then become a TV personality permanently. She's a great singer and a great dancer and she's got great style. She's definitely stealing the show this year."
A source told NOTW online: "It's a case of when rather than if now that Cheryl is doing so well on the show."
And Louis, who used to manage Cheryl, says the stunning brunette has caught the attention of the show's main judge, Simon Cowell.
Louis said: "He definitely flirted with Dannii throughout last year's series. But he seems to have moved on - he's flirting with Cheryl this year. He's definitely paying more attention to Cheryl now, not Dannii."
