Last night Jennifer Lopez looked stunning in silver at the premiere of The Back-Up Plan in Hollywood, and not only did she have her hubby Mark Anthony by her side, but a slew of stars came out to support her!

J. Lo was definitely the best dressed star of the night, or was she? Heidi Klum certainly gave her a run for her money!
