Video: will.i.am f/ Justin Bieber - '#thatPOWER'

will.i.am joins forces with pop megastar Justin Bieber in the futuristic video for “#thatPOWER.” The Black Eyed Peas leader storms cities across the world with a series of clones, performing robotic dance moves in the streets. He beams up a hologram Bieber, who lays down the catchy hook.

“This video is probably the most time-consuming video that I’ve ever been a part of because I had to rehearse choreography, and I’ve always been against choreography for me,” will.i.am told “ET.”

He worked with choreographers Fatima and Rio on the organized dance moves. “We have this real, next-level, futuristic type of choreography,” he said. “It’s not dance, it’s like synchronized movement.”

The dance record will be featured on will’s solo album #willpower, due April 23, along with collaborations with Britney Spears, Chris Brown, Juicy J, Miley Cyrus, Nicole Scherzinger, and Skylar Grey.
