LOS ANGELES, July 21 — Will “The Real Slim Shady” please stand up because we’re really confused on why Harry Potter is as good with a microphone as he is with a wand!

Daniel Radcliffe, best known for his role in the “Harry Potter” film series, was caught on video performing karaoke at an Irish pub in California last weekend with backup from his girlfriend Erin Darke — and it turns out the actor is a real rap wizard.

Radcliffe performed Eminem’s 2000 hit “The Real Slim Shady”, dropping some accurate, if slightly off-beat verses, while Darke jumped in on the chorus and threw down some dance moves.  

A server at the pub confirmed the singer in the video was indeed Radcliffe. This isn’t the first time Radcliffe has showed off his rap skills having nailed a cover of Blackalicious’ “Alphabet Aerobics” on “The Tonight Show Starring Jimmy Fallon” last year.

According to People.com, the actor — who is currently shooting “Swiss Army Man” not too far from the pub where he performed — has long professed his love for hip-hop and “The Real Slim Shady”.
