ET is on the red carpet at the "American Idol" season eight finale with Keith Urban, Fergie and the Black Eyed Peas, Lionel Richie, Brad Garret and season seven "Idol" winner David Cook as the stars reveal who they think will be crowned the next "American Idol".

"Idol" judge Randy Jackson tells ET that he feels both finalists Kris Allen and Adam Lambert have a shot at winning the competition.

"I don't know it could either way today," Randy says. "I almost feel like the underdog being Kris has a shot. It could literally go either way."

Keith Urban reveals that he is a big fan of the show and that he thinks both finalists are talented musicians, but he is rooting for Kris Allen.

"Yeah we've been watching it, this whole season particularly," he says. "My wife got me hooked into it. I'm going to play with Kris tonight so we're rooting for Kris. Adam's a phenomenal powerhouse too so I think it's anybody's shot tonight."

Watch the video to hear reigning "Idol" champ David Cook, season seven runner-up David Archuleta, and ACM's Entertainer of The Year and "Idol" alum Carrie Underwood tell ET what it feels like to be spectators instead of contestants.
