One castle was not enough for this wedding. When megawatt movie star Tom Cruise began dating Dawson’s Creek actress Katie Holmes in 2005, many dismissed the relationship as a publicity stunt. But before long Katie was pregnant, and after the birth of their daughter Suri, the couple turned their attention on planning a wedding for the ages. Old-world style met new-world glitz during the three-day Italian extravaganza in November 2006, which was capped off by a candlelit ceremony in a medieval castle. During the reception, Andrea Bocelli serenaded the Armani-clad couple, and after a fireworks display, the A-list Hollywood crowd moved to a second castle to party into the wee hours. Unlike many of the couples on this list, Cruise and Holmes’ romance is still going strong seven years later.
