Jennifer Lopez: "American Idol" Hollywood Week Hottie

Gearing up for her new television gig, Jennifer Lopez looked glamorous as she stepped out for "American Idol" Hollywood Week in Los Angeles on Tuesday (December 7).

The "Backup Plan" beauty turned up in a curve-hugging white frock and shades as film crews taped her strolling into the hit FOX show's venue.

Making for a change-up to the normal "Idol" schedule, the show is set to be kicked off with a two-night premiere event on Wednesday, January 19 and on Thursday, January 20 at 8:00 P.M. ET/PT.

Another change in the musical talent show is that, for the first time, contestants will be able to get to the Top 12 without having to go through the Top 24 round first.
