Tom Cruise and fiancée Katie Holmes have declared their love for each other in a bizarre “wedding” ceremony — on a ship. The couple exchanged rings emblazoned with triangular Scientology symbols as fellow cult members John Travolta and Kirstie Alley looked on. An insider said: “Katie wore a flowing white dress and Tom was in a black suit as they exchanged rings during the brief 30 minute ceremony. “The couple then walked across a tiny bridge — a Scientology symbol for the journey to total freedom.”
