Last night's Late Night with Jimmy Fallon featured Justin Timberlake as a guest, out promoting his new film, The Social Network.  Timberlake, for those of you who may not watch Saturday Night Live, is one of the funniest and most natural performers of our times, he also happens to be an amazing singer.  In the clips following the jump you can see some of his interview with Fallon, but you'll also get a very special treat.
