The Irish music mogul has been widely tipped to make a comeback to The X Factor this autumn after leaving the show in 2015 following eleven years behind the judges desk.
While nothing has been confirmed about this year's show, Louis has been mouthing off about the programme and claimed it needs to make some changes.
"It dipped a little bit last year. Simon Cowell needs to bring back the original format," Louis suggested. "He needs to have a panel who are fun, to bring Nicole Scherzinger, me and Dermot O'Leary back. And Sharon Osbourne. She's fun and Simon has no control over her."
He added to the Metro newspaper: "I'd go back if it was fun."
The next twelve months sees The Voice UK join ITV alongside The X Factor but Louis doesn't think Simon Cowell has anything to worry about it.
"No, it's boring. All those red chairs swinging round. And they've never had a hit," he complained. "The X Factor churns out hits - not necessarily every year - but it always produces interesting people."
Of course we all know the real best thing about the earlier series of The X Factor was THAT moment between Sharon Osbourne and a rogue door.
The X Factor will be back on ITV later this year but as yet nothing has been announced regarding judges or hosts.
