Jennifer Lopez: 'American Idol' Elimination Shocker!

Jennifer Lopez poses for a quick photo before heading into the studio for the American Idol elimination show on Thursday (April 19) in Los Angeles.

The 42-year-old entertainer wore a cut-out dress the night before during the performance show, which showed off her perfect abs.

Last week, Jennifer and her co-judges Steven Tyler and Randy Jackson used their one save for the season to bring back Jessica Sanchez into the competition. With no save left, one contestant was sent home tonight.
