We've seen Daniel Radcliffe spit rhymes with wizard-esque prowess once before. As it turns out, the actor is no one-trick pony when it comes to rapping. Accompanied by girlfriend Erin Darke, the 25-year-old was recently caught on camera at Cameron's Pub in Half Moon Bay, CA. Darke danced onstage while Radcliffe successfully performed "The Real Slim Shady," to much whooping and applause. His karaoke version of the 2000 hit was totally spot on — right down to the spoken intro. Though we're not sure if Radcliffe's latest lyrical stylings beat his performance of "Alphabet Aerobics" by Blackalicious, we're pretty certain that Marshall Mathers would give his blessing. Also: The world should probably get a petition going for a Harry Potter rap album. It seems like the least J.K. Rowling could do for adoring fans. We have no doubt that Radcliffe and Emma Watson would lay down a killer duet.
