Justin Bieber posts video of Tom Hanks dancing at wedding

All Tom Hanks needed was the piano from "Big" and his performance would have been complete.

Justin Bieber posted a video on his Instagram page Monday of Hanks dancing to Montell Jordan's 1995 hit "This is How We Do It" at a star-studded wedding reception over the weekend.

In his Instagram post, Bieber included the caption, "Haha Tom Hanks singing 'This Is How We Do It' dressed like a Rabbi lol #thatdancetho."

Bieber and Hanks were attending the wedding ceremony in Whistler, British Columbia, Canada for the pop star's manager Scooter Braun and F*** Cancer founder Yale Cohen. Other celebrity attendees included Sophia Bush, Carly Rae Jepsen, Ed Sheeran and Rita Wilson.

Hanks wasn't the only entertainer who took to the mic. Bieber sang The Beatles classic "All You Need is Love" and later performed a rendition of "Call Me Maybe" with Jepsen.

Bieber also shared several photos from the event, including some shots with the likes of Cohen and Sheeran:
