Comedian Jimmy Kimmel pranked guests at his wedding ceremony on Saturday (13Jul13) by pretending he was exchanging vows with actress Gabourey Sidibe.

The Precious star, a regular guest on Kimmel's U.S. chat show who once dressed up as Adolf Hitler for a comedy skit, turned up to the nuptials in Ojai, California in a wedding dress and stunned guests including Ben Affleck, Matt Damon, Jennifer Aniston and Emily Blunt and their partners when she started walking down the aisle as the ceremony began.

Joking aside, the Jimmy Kimmel Live! host exchanged vows for real with Molly MCNearney in Ojai, California as several of his famous friends looked on.
