Justin Timberlake And Jimmy Fallon Give Us The "History of Rap"

Justin Timberlake never fails when he hits up late night TV.

First, it was "D*ck In A Box" with Andy Samberg which became somewhat of a spinoff for him on Saturday Night Live and most recently, JT impresses us as one half of a rap duo which features the hilarious Jimmy Fallon.

Justin and Jimmy showed off their rap skills last night on Jimmy's Late Night With Jimmy Fallon in their third installment of "History of Rap."

The duo first featured their "History of Rap" segment back in October 2010 when Justin was on the show, the second installment came this past July and last night the two worked it for the third time.
