As if that's not a crazy picture in itself, the Biebs actually caught Tom dancing at the party, and posted a video of the whole moment on his Instagram. What's even better than seeing Tom bust a move, is the fact that he's singing and dancing to Montell Jordan's "This Is How We Do It" in it. Oh, and his outfit is pretty much the swaggiest thing we've ever seen. Don't tell Justin.
"Haha Tom Hanks singing 'This Is How we do it' dressed like a Rabbi lol #thatdancetho," Bieber captioned the vid.
Watch Justin's clip of Tom getting down at Scooter's wedding below. You can thank him for the laugh.
