Jimmy Fallon is a lip synching machine! The guy has battled it out on the lip sync mat with everyone from Joseph Gordon-Levitt to Will Farrell and Tom Cruise. And now he's setting his sights on taking on the biggest name in daytime talk shows - Ellen DeGeneres 

It was pretty much a given with Ellen's visit to the Tonight Show that Jimmy would rope her into some sort of goofy game.  She'd obviously kick his ass if he challenged her to a dance battle, so pretend singing it won out. 

Jimmy did pretty well with Silentó, but then Ellen came on and smoked him with Rihanna.
