Just Dance 4 has Bieber Fever

This may be one of the funniest promotional videos I've seen in quite a while. With Just Dance 4 launching today in North America, Ubisoft has released a new video that shows the power of Justin Bieber.

In the video, a bunch of girls — Beliebers, I believe they are called — are invited to what they think is a focus group, or play test, for Just Dance 4 — specifically for the Justin Bieber song "Beauty and a Beat"…ha…

What they don't know is Justin Bieber is right behind the mirror watching their dance moves. He then surprises the girls, some of them breaking down into tears just from being in the same room as the boy wonder. I seriously can't believe the reaction some of them have to seeing him.

There is a point to all of this; Ubisoft has announced Just Dance 4 as an official sponsor of Justin Bieber's "Believe" Tour in North America. The sponsorship is highlighted by the "Just Dance to Justin Sweepstakes" which lets you enter a sweepstakes onthe Just Dance Facebook Page for a chance to meet Justin.

If you've got Bieber Fever, you need to watch this video. Just Dance 4 is available for Xbox 360, PS3, and Wii. The game will also be released for the Wii U sometime during the system's "launch window".
