Steven Tyler, Jennifer Lopez Draw Celeb Viewers To 'American Idol'

'Let's not doubt J.Lo. I bet she's got claws!' Gabby Sidibe says of new judge.

Jennifer Lopez and Steven Tyler made their big "American Idol" debuts on Wednesday night, and regular fans and "Idol" alums weren't the only ones tuning in for the big premiere. Based on the people we spoke to at Sunday night's Golden Globes, there were some very famous eyes glued to the set too.

"My faith in 'American Idol' has been restored," "Precious" star Gabby Sidibe told MTV News. "They switched it up with the judges, and now I'm interested again."

Sidibe went on to praise J.Lo's potential as a judge. "Let's not doubt J.Lo. I bet she's got claws! Let's see."

"Mad Men" star Jon Hamm said he'd be tuning in. "Well, they've certainly shaken it up this year," he laughed. "So we'll see what happens."

Paris Hilton and Jennifer Love Hewitt both said their adoration for Jenny from the Block would keep them watching the show. "Jennifer Lopez is just like the yummiest thing to look at ever," Hewitt gushed. "So I just wanna look at her be pretty!"

"Now that she's on, I'll definitely tune in," Hilton said.

Jenna Ushkowitz of "Glee" thought that having two veteran performers judging the contestants provides "Idol" with artistic credibility. "I think J.Lo and Steven Tyler will put in a lot of really, really good criticism because they're performers," she said. "I think it'll be constructive, and I think it'll be helpful."

Jake Gyllenhaal and Keri Hilson were two famous fans that admitted to being a little apprehensive about the changing dynamic of the show.

"There is a missing juggernaut amongst things," Jake quipped, alluding to Simon Cowell's absence. "But I think, you know, there's always a need for change in everything. ... I think that always is an important thing, and you know, even when you tear the heart out of something, you never know where the heart might find itself again."

Keri added skeptically, "We'll see how it pans out. I mean, you've got to have a jerk. You kind of have to have someone who will be brutally honest."
