Daniel Radcliffe may be a muggle, but as he's hinted at on Fallon appearances, he does have some tricks up his sleeve.

As Vulture informs us, the actor — who probably doesn't love the Harry Potter references anymore, you guys — performed a karaoke rap a few days back while in Half Moon Bay, California following a visit to San Diego's Comic-Con.

The venue was Cameron's, a British Pub that's as close as you can get to Hogsmeade without apparating out of the Bay Area. At the bar, which incidentally is the same one Gerard Butler spent a great deal of time at while shooting Chasing Mavericks, Radcliffe dropped his knowledge of "The Real Slim Shady."

In the past, the actor has idly remarked on his love of Eminem. But here, Radcliffe proves it, and he's ably accompanied by his girlfriend, the actress (and quite the dancer) Erin Darke.
