So you think Ellen DeGeneres can dance? She sure can! Check her out doing a hip-hop routine on last year's So You Think You Can Dance finale to Lil Jon's (featuring LMFAO) "Outta Your Mind."

Ellen did the dance in honor of promising SYTYCD contestant Alex Wong, who had to leave the show abruptly after rupturing his Achilles tendon.

"It broke my heart when I saw his injury and as a joke, I said it would be fun and because of [SYTYCD choreographers] Napoleon and Tabitha, it became a reality," she said.

Before Ellen went on to become a judge on American Idol in 2010, she appeared as a guest judge on the hit dance contest during week seven of the 2009 season.
