J Lo Wears Sexy Sequins and Says Goodbye to Elise Testone on Idol

Jennifer Lopez made her way to the set of American Idol in Hollywood last night in a short, sequin minidress. It's her second sexy outfit of the week following her Wednesday appearance in an ab-baring ensemble. Idol hopeful Elise Testone was the latest to be sent home — do you agree with the results? — which leaves five contestants still in the running for this year's title. Katy Perry dropped by earlier in the week and taped a performance of her hot track "Part of Me," which aired during the results show.

J Lo's been mentoring the singers all season, and next week she'll take the stage and show off her own singing and dancing skills. She's planning to perform her latest track, "Dance Again," alongside boyfriend Casper Smart. Jen's been practicing the choreography with her dancers and even invited them to her home last weekend for a shirtless and bikini-filled barbecue!
