Many of Hollywood's hottest couples hit the red carpet in LA yesterday for the premiere of Iris, a new production from Cirque du Soleil. Matthew McConaughey threw on a fancy vest to pose alongside his sequined ladylove Camila Alves, while Cindy Crawford and Rande Gerber shared an afternoon out with their kids. Christina Hendricks posed with husband Geoffrey Arend, as did Neil Patrick Harris and David Burtka. NPH was impressed with what he saw, basically tweeting a rave review. He wrote, "Just saw the premiere of Cirque du Soleil's new show Iris. It's ammazing! If you come to Hollywood, it is a must see! Best show in years!" Recently single Joe Manganiello was looking hunky before the show began, and he was able to mingle with some other single stars like Vanessa Hudgens.
