Daniel Radcliffe raps 'Alphabet Aerobics' on 'Tonight Show'

Daniel Radcliffe knows the alphabet—and performed a complicated rap song on Tuesday to prove it.

The Horns star went on The Tonight Show Tuesday evening and revealed that he’s always had an “obsession” with memorizing tricky rap songs, including Blackalicious’ “Alphabet Aerobics.” So, of course, Jimmy Fallon made him show off his skills.

“Alphabet Aerobics” is a fast-paced song filled with tongue twisters, but Radcliffe nailed the performance—even when the tempo picked way up at the end. Daniel Radcliffe: movie and rap star.

Horns arrives in theaters Oct. 31.
