The love boat.

Has Katie Holmes secretly already become the third Mrs. Tom Cruise?

The National Enquirer is reporting that the two were married last summer while cruising in the Caribbean. The couple, who at that point had been together only for a few months, were aboard Scientology ship Freewinds when the happy day took place, officiated by a chaplain of the controversial cult, er, religion. After officially becoming husband and wife, at least per the standards of L. Ron Hubbard, Tom and Katie shared a walk on a small bridge, emblematic to those who practice Scientology of "total freedom" (for those who don’t practice the religion, it’s emblematic of simply getting from one place to another). While fellow Scientologists John Travolta and Kirstie Alley were supposedly also aboard the ship, there were no Cruise or Holmes relatives present.

When asked for confirmation, sources for TomKat deny that the two are already hitched and say that the couple is still working on their plans for the big day. Not to be confused, of course, with plans for the big day Mission Impossible 3 premieres. Oh, the irony…
