Pink, Justin Bieber, Selena Gomez and Sean 'Diddy' Combs apparently feature on the "dream team" panel that he believes will revive the struggling Fox series.
Mariah Carey, Nicki Minaj and Keith Urban joined original judge Randy Jackson at the beginning of this season, but the singing competition continues to lose viewers.
"It's been a lacklustre season for Idol and everyone involved with the show is well aware of it so that's why producers are frantically working on lining up big name stars for season 13," a source told Radar Online.
"There's more drama going on behind the scenes of the show than on the stage, and that's why there's a major overhaul in the works.
"A telling sign was that the highlight of the season was Mariah and Nicki's explosive feud that was leaked on the web - and that was before the season even aired.
"Producers have been trying to recreate that buzz ever since and it hasn't worked - the public isn't buying it. The judges don't have real chemistry, and there's no real standout contestant.
"That's why they want to go big next season, and you can't get any bigger than Justin Bieber. The executives are calling it their dream team because who wouldn't tune in to see Justin and Selena, Pink and Diddy?
"Pink has been approached in the past and turned it down as well as Diddy, who wanted too much money. It will cost a fortune to get them, but the show has gotten so stale that Fox is desperate for a revamp - they're willing to pay to put Idol back on top.
"Idol is not the water cooler show it used to be - it's not hip and become really boring. If producers have it their way, Justin, Selena, Pink and Diddy will be sitting at the judges' table next season and that's a powerhouse group and everyone would tune in to see."
It was recently reported that Fox bosses were secretly planning to replace Carey with former judge Jennifer Lopez for the remainder of season 12.
