Who knew Harry Potter was a hip-hop star?

While promoting his upcoming horror flick “Horns” on Tuesday night, Daniel Radcliffe hit the “Tonight Show,” where he and host Jimmy Fallon dished about his love of music — and rap in particular. While chatting with Fallon, the self-proclaimed Eminem fan also revealed his unique obsession of memorizing the complicated lyrics to fast songs. Among the swift jams that Radcliffe has mastered? Blackalicious’ “Alphabet Aerobics.”

Channeling his inner Slim Shady, Radcliffe then took to the stage and put his skills to the test by reciting the lyrics to the Blackalicious tune as Fallon held up alphabet cue cards in the background. After a nearly flawless performance, Radcliffe was met with a standing ovation.

Check out Radcliffe’s epic rap in the video above.
