Ananova:

Tom Cruise and Katie Holmes have taken part in a "wedding" ceremony - on a ship.

They exchanged rings emblazoned with triangular Scientology symbols.

Scientology members John Travolta and Kirstie Alley witnessed the ceremony.

According to The Sun 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."

Katie, 27, who is due to give birth in a few weeks, entered to a traditional bridal march. Afterwards they feasted on steak and lobster.

Katie and Tom plan to wed for real later this year.

Asked about the ship ceremony, a spokesman for Cruise said: "All I can say is they are not married in any sense of the word."
