Stephen Merchant Wears Leather Chaps While Singing Christina Aguilera's "Dirrty" on Lip Sync Battle

Stephen Merchant wasn't afraid to play dirty when he faced off against Malin Akerman on Thursday's episode of Lip Sync Battle. After Malin gave an amazing performance of Jason Derulo's "Talk Dirty," Stephen took things a step further when he channeled the original dirty girl herself, Christina Aguilera. Donning leather chaps and a tank top featuring the British flag, Stephen made his grand entrance in a cage surrounded by women. He then began thrusting his hips and impressively singing Christina's 2002 hit "Dirrty" almost word for word. Watch the hilarious battle above, then check out Terry Crews delicately singing "A Thousand Miles" by Vanessa Carlton.
