Matt and Luciana Damon held hands as they walked around St. Lucia on Sunday. The couple were all smiles after celebrating a special occasion with friends and family. Matt and Luciana renewed their wedding vows at the island's Sugar Beach resort on Saturday following more than seven years of marriage. Their four children were in attendance and there were also plenty of celebrity pals on hand to witness the event, including Ben Affleck and Jennifer Garner, Chris Hemsworth and his wife Elsa Pataky, as well as Don Cheadle and Casey Affleck. The star power didn't end there since Jimmy Kimmel officiated the ceremony. Ben, Jennifer, Chris, and others were spotted leaving the Caribbean on Sunday, though it looks like Matt and Luciana stayed behind to enjoy their newly remarried status.
