Justin Bieber posts video of Tom Hanks dancing to "This Is How We Do It" at wedding

This video has everything: Tom Hanks, Justin Bieber, a yarmulke and "This Is How We Do It."

Yes, you read that right (and no, this isn't Stefon speaking). The star of cinematic treasures Forrest Gump, Cast Away and Sleepless in Seattle busted a move to Montell Jordan's 1995 jam – and the Biebs got it all on camera.

What event could possibly bring Hanks, 57, and the pop singer together? The wedding of Bieber's manager Scooter Braun and cancer activist Yael Cohen, who tied the knot in Canada over the weekend.
