Having to wait around in airports is no fun -- unless you're one of Justin Bieber's back-up dancers. Instead of moping around when their flight to Washington, D.C. was cancelled, the Biebs' dance troupe decided to do something a little crazy. The crew performed their dance to "Beauty And A Beat" in front of the entire terminal, and recorded a video that quickly went viral. Check out the video above to see for yourself.
In other awesome airport flash mobs, this summer, a group of dancers at Vancouver Airport broke out into a flash mob for the Queen's Diamond Jubilee. And in February, a group of Delta Airlines employees broke into a dance choreographed to a song written by one of their own.
