Tom Cruise & Katie Holmes: Odescalchi Castle in Bracciano, Italy

The world came to a screeching halt that chilly Saturday evening on Nov. 18, 2006, when Thomas "Tommy" Cruise Mapother IV—once considered the world's hottest man and now deemed the craziest by some—wed girl-next-door Katherine "Katie" Noelle Holmes at a majestic castle on Lake Bracciano. Some of the duo's closest pals, like Will Smith and wife Jada, Kelly Preston and hubby John Travolta, and Leah Remini made the trans-Atlantic trip for the occasion. Opera sensation Andrea Bocelli sang at the service, while the couple's daughter, Suri, who was seven-months-old at the time, cruised the carpet on all fours—clad in Armani.
