Watch Justin Bieber and Boyz II Men Perform on ‘Dancing With the Stars’ [VIDEO]

<SPOILER ALERT!> Before David Arquette was officially booted from last nights Dancing with the Stars, the audience in the studio and those of us watching at home were treated to a performance by Justin Bieber and Boyz II Men.

Sporting a new spikey hairdo, Justin took the lead as the group performed the song "Fa La La" from Justin's Christmas album, Under the Mistletoe, in stores now.
