Justin Bieber in Zubaz pants - LMFAO Party Rock on American Music Awards

By Rickey ·

Justin Bieber in Zubaz pants danced with LMFAO at the 'Party Rock' finale of the 2011 American Music Awards! Best moment on TV this year! LOL!

Keenan and David Hasselhoff also joined in. And of course Quest Crew were the backup dancers. I loved this! What an ending! Go Bieber! Go Bieber! Go Bieber!
