Daniel Radcliffe shows rap muscle with ‘Alphabet Aerobics’

Daniel Radcliffe just cast another spell on audiences, but this time he did it with his mad rap skills.

The “Harry Potter” alum, goaded by host Jimmy Fallon, performed Blackalicious’ complex “Alphabet Aerobics” on “The Tonight Show” on Tuesday.

Fallon asked the “Horns” and “What If” star about his interest in music, and Radcliffe surprisingly admitted that he was into Eminem and was one of the first people in his class to learn all the lyrics to “The Real Slim Shady.”

“I’ve always had kind of an obsession with memorizing complicated, lyrically intricate and fast songs, I guess,” the 25-year-old said. “It’s a disease.”

The audience giggled, and that’s when Fallon suggested “Alphabet Aerobics” as a true test of Radcliffe’s claims. So the British star threw down the gauntlet, removed his blazer and delivered an impressive and impeccable cover of the alliterative 1999 rap while Fallon displayed letter-emblazoned cards to track Radcliffe’s progress through the alphabet.

The performance was worthy of the Roots front man Questlove, whose band delivered a “Harry Potter” rap last June. Questlove sent a tweet to the Blackalicious artists to tune in for Radcliffe’s performance.

“dear @realgiftofgab & @ChiefXcel make sure you and the entire @blackalicious_ fan base watches & dvr’s #FallonTonight. trust. #!!!!!!!!” he wrote.

Radcliffe also dropped his British accent along the way, and -- speaking of accents -- the actor and Fallon swapped impressions during the interview, with Radcliffe explaining that he learned to do an American accent while growing up by watching WWF wrestling. (His “Potter” costar Emma Watson learned hers from “Keeping Up With the Kardashians.” What does this say about our across-the-pond exports?)

The young star also said that he’s a huge fan of Dwayne “The Rock” Johnson -- an admission that drove Fallon to say that a band movie called “Rock ‘n’ Radcliffe” would be a good idea.
