WATCH: Ellen Degeneres Does Her Best Rihanna in Lip Sync Battle Against Jimmy Fallon

Ellen Degeneres brought down the house on Jimmy Fallon last night as they duked it out in a Lip Synch Battle, judged by Justin Timberlake.

Doing a particularly impressive impression of Rihanna and lip synching “Bitch Better Have My Money” in the second round, Degeneres ended with a perfect mic drop and seized the win.

In the first round, Degeneres showed off her softer side with Diana Ross’ “Theme from Mahogany (Do You Know Where You’re Going To).”

Fallon, meanwhile, showed off his cool kid skills with Silentó‘s “Watch Me (Whip/Nae Nae)” and The Killers’ “Mr. Brightside.”

Watch Degeneres and Fallon go head to head in the video above.

Also on Fallon last night, Timberlake revealed the most adorable photos of his and Jessica Biel’s baby Silas, while Macklemore & Ryan Lewis were last night’s musical guests.
