The "American Idol" judges' table has felt like a game of musical chairs in recent weeks as producers work to fill out the panel for the upcoming twelfth season, and new reports say pop star Katy Perry turned down a whopping $20 million to join the show.

TMZ reports that producers initially offered Perry $18 million, but when she didn't bite, "Idol" upped the ante and offered $20 million for one season. That's $2 million more than already confirmed judge Mariah Carey will receive.

But Perry, 27, reportedly said she wasn't interested no matter how much the show offered. She's already given judging a singing competition a chance when she appeared as a guest judge on the UK version of "The X Factor," and she didn't feel that joining "Idol" would be the right choice for her.

It's likely Carey would not have been happy with Perry's selection. Not only would the "Firework" singer have surpassed Carey's salary, but Mariah is already enraged about the possibility of rap superstar Nicki Minaj joining the show.

Reports say Carey was promised she would be the only woman on the judging panel, and she thinks Minaj would steal the spotlight from her.

Carey has allegedly made suggestions to producers about who she would prefer to sit alongside her, including Lenny Kravitz and Enrique Iglesias.
