Hollywood couple Tom Cruise and Katie Holmes are planning a Scientology weeding scheduled for next month at the Scientology headquarters in Los Angeles.

Tom, 43, start to date Katie Holmes, 26, in April 2005 and after only three months, he proposed her at The Eiffel Tower. Katie Holmes decided to convert to Scientology encouraged by Cruise.

A source at the Scientology center says: "Tom has encouraged Katie to embrace our faith and they have agreed to a Scientology wedding service."

"It has become a prerequisite of Tom's that the closest people in his life should also be scientologists. He was mortified when Nicole turned her back on his faith but is overjoyed that Katie has embraced it."

Katie Holmes will be the the third wife for Cruise, who has previously been married with actresses Mimi Rogers and Nicole Kidman.

Rumors said Nicole will not attend her ex-husband's weeding. A spokesperson says, "I'd be surprised (if she would attend). I'd say it's not on the cards."

Tom Cruise and Katie Holmes will spend their honeymoon on a luxury yacht.
