What a jolly giant!
Despite having like a 3-foot height differential, Justin Bieber got his dance on with basketball star (and fellow Twitter addict) Shaquille O'Neal.
It's all for the the upcoming season of Shaq Vs., where he takes on JBiebz and crew in a Step Up-like showdown.
And the big man has mad moves! Check it all out at the 1:00 mark. Hope Justin doesn't get stomped on by accident...
