Kanye West Turned Down American Idol Because He "Didn't Want to Go That Mainstream"

But knocking up Kim Kardashian and appearing on her mom's talk show is ok? Hmmm...

Kanye West was offered the third and final spot on American Idol's judging panel for the upcoming 13th season, according to a source for Us Weekly. Wait, there's not going to be a fourth judge?!

"He didn't want to go that mainstream," the insider says. "He didn't want to lose any street cred. So he turned it down." Ha!

Keith Urban will return to the show, and after taking a season off, Jennifer Lopez will be back as well. Still no official confirmation from J. Lo's camp, but everyone from Entertainment Weekly to E! is reporting that it's a done deal. As you know, Nicki Minaj, Mariah Carey, and Randy Jackson are all leaving the show, and producers reportedly interviewed Will.i.am, Diddy and Rodney Jerkins for Randy's spot. However, they're now in serious negotiations with Dr. Luke, who's worked with stars like Britney Spears and Katy Perry.
