Daniel Radcliffe's rap skills are pretty magical

No spells or wizardry were used in the making of this video -- it just turns out that Daniel Radcliffe is a really, really good rapper.

The "Harry Potter" star, now promoting his new film "Horns," admitted during an appearance Tuesday on "The Tonight Show Starring Jimmy Fallon" that he's a big fan of rap music.

"Initially I got into Eminem and was obsessed with learning all the words to 'Real Slim Shady,'" Radcliffe, 25, explained, adding, "I've always had an obsession with memorizing complicated and intricate fast songs. It's a disease."

You can't say something like that in front of Jimmy Fallon without expecting to demonstrate, and the host suggested Blackalicious' 1999 hit "Alphabet Aerobics."

Radcliffe gamely removed his jacket and grabbed a mic before blazing through the song (in an American accent, too) as Fallon stood behind him holding cue cards with each letter of the alphabet as the audience clapped and cheered him on.
