NEW YORK – Jimmy Fallon and Justin Timberlake are the hottest duo in hip-hop — for the moment.

They performed a medley of rap hits on “Late Night With Jimmy Fallon” Wednesday, and the clip is becoming a viral hit.

Fallon and Timberlake started off with Sugarhill Gang’s classic “Rapper’s Delight” and then performed jams from artists including the Beastie Boys, the Notorious B.I.G., Jay-Z and Eminem.

Fallon, 36, said he’s surprised by the success of the skit.

“We never know what’s going to viral or get picked up, and this one’s beyond what we thought it would do,” he said Thursday.

Though the clip looks all fun, he said, he took the time to get it right before taking the stage.

“You know I really needed to practice. You know I can’t rap,” said Fallon, who also performed songs by Missy Elliott, Tupac, Kanye West and Snoop Dogg. “I was in my apartment till 2 in the morning the night before doing (the) Soulja Boy (dance) and my wife was like, ‘You’re crazy!’ “

The performance was backed by the house band for the NBC show, the Grammy-winning hip-hop group The Roots.
