Olivia Munn knew just what song to do to get everybody in a nostalgic mood on the latest episode of Lip Sync Battle. In a preview for her battle against Kevin Hart [1], which airs Jan. 14 on Spike, the actress takes it back to 2002 and performs "Dilemma," Nelly's classic song with Kelly Rowland [2]. Olivia dances around the stage in leather pants, a baseball hat, and, of course, Nelly's signature eye band-aid. Watch her in action above, then check out Beyoncé's surprise appearance during Channing Tatum's episode [3].
