The Jonas Brothers and Demi wanna see you bounce!

Joe Jonas and Demi Lovato add fuel to the fire of rumours that they're dating, as the Disney lady joins him, his brother Nick and JoBro's bodyguard Big Rob for the funniest music video we've seen... ever!

With lyrics like, "I'm the kind of guy that likes to bounce! Now I'm the kind of guy that's got a pet mouse!", it's probably not the most lyrically strong track from any of these artists, but it sure is funny!

Dressing up in wigs, glasses and general comedy gear, the stars rap their way through this video and throw in a bit of break-dancing, too! Watch the video for Bounce here, and look out for Big Rob's solo!

We think the Jonas Brothers and Demi friendship is so cool! We love how she can joke around like one of the guys.

Wonder why Kevin didn't join in with the rapping and dancing though? Maybe he was busy with plans for his wedding to fiance Danielle Deleasa?!

Did you enjoy the video? Do you think there's romance between Joe and Demi?
