You got served! Even though her moves are a staple on her show, Ellen DeGeneres surrendered the floor on Thursday, Sept. 18, to two other stars: Kevin Hart and Josh Gad, who competed in Ellen's very first dance-off. 

"I've never talked about it before, but I've recently become the commissioner of the North American Dance Society — or NADS," she explained to her audience. "As commissioner, I'm responsible for officiating all dance-offs, and today I've been asked to settle a dispute between two hilarious guys." 

The funnymen, who costar in the upcoming film The Wedding Ringer, competed to Pitbull's 2009 hit "I Know You Want Me (Calle Ocho)." 

The 35-year-old Ride Along star kept it cool with popping and locking moves, while Gad, 33, pulled out all the stops by grinding on the floor, topped off by some "Gangnam Style" horsey dancing.
