Jimmy Kimmel and show writer, Molly McNearney, tied the knot this past weekend in California. Ben Affleck, Jennifer Garner, Jennifer Aniston, Justin Theroux, Matt Damon and his wife Luciana, Ellen DeGeneres, Portia de Rossi, Dax Shepard, Kristen Bell, Johnny Knoxville, Emily Blunt, John Krasinski, and more were all guests at the Kimmel wedding. Gabourey Sidibe even pulled a prank on the funny man by showing up the ceremony in a wedding dress. Check out some pics from the wedding in the gallery. Congratulations to the happy couple!
