The clip shows Justin and Selena dancing around to the upbeat song, but the the two are not alone. They're also joined 由 the likes of Ashley Tisdale and several members of Big Time Rush.
It's hard not to want to jump around with them -- the single is almost reinvigorated 由 the footage of Justin & Co. having oh-so-much fun. There's even a scene where The Biebs and Sel look like they're about to 吻乐队（Kiss） -- that is, until Ashley breaks it up.
