will.i.am performed his new single '#thatPOWER' on 'Dancing With the Stars' last night. With a virtual Justin Bieber, I felt it was some kind of trickery, but it was almost like the Biebs was there...

Really liking this song, we have been playing it on K-Fox for over a week now.  If you have seen the video, the performance was just like it.  will.i.am had look-alike dancers, who were perfectly choreographed. They did wear some weird Hammer pants, with the low-hanging crotches.

While it was quite the spectacle, this performance was really about the intricate choreography and the incorporation of the virtual Bieber. Check it out above!
