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” last night, 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. I think it is AWESOME. Check out the video below!
