Note: Randy Jackson has agreed to step down as a judge and to serve as a mentor for American Idol, which means that he is not leaving the show, as the original question asked. Therefore this will be cashed out at "no."

YOU DIDN'T THINK it would happen, but it did. Stephen Tyler announced he was done with "American Idol" on Friday, July 13. (And given that it's Tyler, perhaps the date was intentional.) In typically colorful fashion, Tyler proclaimed sadly that, "I’ve decided it’s time for me to let go of my mistress ‘American Idol’ before she boils my rabbit" -- and now he's going back on the road with the band. All of which begs the question: what will happen to Jennifer and Randy? It's a tough call. JLo is among the savviest businesswomen in Hollywood, and you can bet she's determined to get what she's worth, all of which could make it hard to stitch together a deal. Randy for his part has always been the sidekick, but perhaps he's sick of that and wants to headline this sucker once and for all -- all of which could cause problems. We're not sure how it will unfold, but we do expect a lot more public handwringing, as both sides gauge media reaction and try to see how badly the public wants "Idol" to retain its stars. Prepare for drama as the eliminations begin.
