Watch Jimmy Fallon Face Off with Ellen DeGeneres in an Epic Lip-Sync Battle

On Wednesday night, "Tonight Show" host Jimmy Fallon battled daytime talk show host Ellen DeGeneres in an epic lip-sync battle.

The battle was judged by no other than music legend Justin Timberlake.

The comedians did not know what songs each other picked until they took the mic.

Fallon started the battle with his rendition of The Killers' "Mr. Brightside."

DeGeneres followed with Diana Ross' not so upbeat song "Do You Know Where You Are Going To?" – making the battle even more hilarious.

But the song choices that followed were what made the lip-sync battle absolutely epic.

Fallon’s second song choice was "Watch Me (Whip/Nae Nae)" by Silento.

DeGeneres ended the battle with her "rendition" of "B*tch Better Have My Money" by Rihanna.

Watch the lip-sync battle in the video below to see who Justin Timberlake declared the winner:
