Perhaps two of the funniest people, going head to head in a lip sync battle? Yes, please! Jimmy Fallon is pulling zero punches in his premiere week with The Tonight Show. Always fun and entertaining, he is stepping his game up and Stephen Colbert and Jimmy Kimmel better be ready. Last night, along with the ‘History of Rap’ with Justin Timberlake, he also had Ellen DeGeneres on and they had an epic lip sync battle. While Jimmy Fallon took on The Killers and Silento, DeGeneres took on Diana Ross and Rihanna. With Timberlake judging, it all made for a good time.
