Maria Shriver and Arnold Schwarzenegger are arguably America's most powerful celebrity couple. She's a member of the nation's foremost political family, and he's the world's only bodybuilder who also happens to be an A-list movie star and former governor.
The two legally joined forces in a Roman-Catholic ceremony in April 1986, in Hyannis, Mass., in front of 400 guests. The bride wore a gown with an 11-foot train. Guests included many notable names from the Kennedy clan, including Shriver's cousin (and JFK's daughter) Caroline Kennedy, who served as maid of honor, Oprah Winfrey and Andy Warhol. Despite being extremely health-conscious, the future Governator and his bride splurged on a 450-pound wedding cake. Now, that's something to get pumped up about!
