The truTV reality show combines the art of dance, aerobics, puppetry, technology and talent in an exciting and innovative take on live performance art. 

Casper serves as a judge on the show alongside creative director and choreographer Laurieann Gibson and Glee star Harry Shum Jr. In this exclusive behind the scenes clip, the three dancers just can't sit still for too long in those judges chairs and face off in an impromptu dance off!

Over the weekend, Casper spoke to ET on the Billboard Music Awards red carpet about the exciting new show. "It's such a talented, well-rounded show," he told ET’s Cameron Mathison. “There’s no age limit so it doesn't put anything in a box and doesn't pigeon-hole. It's a lot of energy and it happens quick so it's very engaging."

Watch the full moment in the clip above. Catch new episodes of Fake Off on Wednesdays at 10/9C on TruTV.
