Nicole Richie's Man Chest Outfit on Lip Sync Battle Can't Be Unseen

Nicole Richie pulled out all the stops when she competed against John Michael Higgins during Thursday night's Lip Sync Battle. While her Great News costar performed a groovy version of Tom Jones's "It's Not Unusual" (complete with the world's tightest pants), Nicole really stole the show with her Marky Mark impression. Singing "Good Vibrations" by Mark Wahlberg's hip-hop group, Marky Mark and the Funky Bunch, she threw it back to the '90s with a muscle t-shirt, baggy jeans, and a lot of pelvic thrusts. We definitely think Mark would be proud of those moves.
