TomKat -- The Honeymoon's Over!

Tom and Katie are quite over ... their honeymoon, that is. The Cruise's fairy tale post-nuptial cruise in the Republic of Maldives was ruined by endless thundershowers.

The newlyweds and baby Suri made their getaway from the rain-soaked paradise and jetted back to sunny Beverly Hills -- on Tom's private plane, of course.

Apparently, he borrowed John Travolta's outfit from "Saturday Night Fever."
