Ellen DeGeneres Ellen DeGeneres

Jimmy Fallon pulled out all the musical stops on The Tonight Show Wednesday night. Not only did he and Justin Timberlake team up to perform "History of Rap 6," but the episode also included a heated lip-sync battle between Fallon and Ellen DeGeneres.

Fallon selected The Killers' "Mr. Brightside" and Silento's "Watch Me (Whip/Nae Nae)," but despite his best efforts (and an attempt to bribe Timberlake, who was judging the contest), he was no match for Ellen, who tackled Rihanna's "Bitch Better Have My Money" with aplomb.

Before breaking into "Bitch," Ellen also performed Diana Ross' "Do You Know Where You're Going To," while sitting cross-legged on the stage.
