Katie at a loss for words over Tom

NEW YORK - The future Mrs. Tom Cruise has already tried on at least one wedding gown.

Katie Holmes appears in the August issue of W magazine posing in a Commes des Garcons wedding dress and continues to gush about her fiancé. The couple, who went public with their relationship in April, haven’t announced a date for their marriage.

“Tom and I will always be in our honeymoon phase,” Holmes says in W, on newsstands July 22. In the interview, a theme emerges with many similar comments, including “Tom is the most incredible man in the world.”

Cruise, 42, and Holmes, 26, became engaged last month after the “War of the Worlds” star proposed at the Eiffel Tower in Paris. Holmes, who co-stars in “Batman Begins,” has said she’s taking lessons in Cruise’s faith of Scientology.

“I’m learning to celebrate my own spirit, my own being,” she says.

During the W interview, the actress wouldn’t part from Jessica Rodriguez, who is described as her “Scientologist chaperone.” Rodriguez’s role in Holmes’ life remains vague, though Rodriguez says they’re “just best friends” since meeting around the time Holmes met Cruise.

“You adore him,” Rodriguez told Holmes when the actress was at a loss for words to describe her love.

Not to forget their day jobs, Holmes says she wants to make a movie with Cruise.

“That would be such an honor,” she says. “Such an honor.”
