One thing we can and should all agree on: Naya Rivera is the best part of Glee this season. Look what she did with “Nutbush City Limits.†And “Girl on Fire.†And “Mine.†And Santana is still the best bitch-slapper on the show. In Thursday’s new episode of Glee, she puts that bitch-slappery to song, dedicating Paula Abdul’s “Cold Hearted†to the talcumy hairless boy wonder Brody. Watch Vulture’s exclusive video of the performance below. It features fishnets and scaffolding, good for writhing around. You’re welcome.
