David Guetta, Ellen DeGeneres, and Usher

Usher and David Guetta Perform ‘Without You’ on ‘Ellen’ [Video]

Usher joined forces with David Guetta to perform their chart-topping smash “Without You” on Tuesday’s “Ellen DeGeneres Show.” Looking sharp in all black, Ursh emerged from the smoke as laser beams shot across the stage, with the French DJ working the turntables behind him. Ellen even got in on the fun at the end. They will do it again tonight on “Jimmy Kimmel Live!”
