Jennifer Lopez Sexy Black Dress American Idol Pictures

Jennifer Lopez, Randy Jackson, and Steven Tyler were back behind the judging table last night on the latest nerve-wracking episode of American Idol. The seven remaining contestants performed songs from 2010 to present day including covers of popular tracks by Kellie Pickler, Maroon 5, and Lady Gaga. The judges had a hard time predicting who might go home, but we'll find out later today when the results are revealed. Fan favorite Phillip Phillips had a less than stellar performance while Elise Testone, who's been in and out of the bottom three each week, got high marks from the judges.

J Lo often has friends, family, and boyfriend Casper Smart visiting her on the set or sitting in the audience and last night was no exception. J Lo was joined by best friend, and actress, Leah Remini, who chatted with her before and after the taping. Leah watched the show from backstage, tweeting photos and joking with her followers, "Backstage at American Idol watching my annoyingly pretty and talented friend do her thang'."
