"I've got some things planned. I've got some things planned tonight," Cruise said Wednesday on Ryan Seacrest's KIIS-FM radio show. "I've been kind of surprising her throughout the week with things."
Asked his advice on wooing a woman, Cruise, 46, says, "I like romance. You gotta think about these things. You've got to know the right thing and pay attention throughout the year ... and just know your lady."
Holmes, whose birthday is Thursday, will be performing in All My Sons on Broadway as she celebrates the big 3-0. Cruise is due in L.A. Thursday for the Hollywood premiere of his movie Valkyrie.
One thing Cruise cautions against is putting information about birthday surprises on one's BlackBerry. "It's wrong, man," he tells Seacrest. "You can't do that – not unless you are trying to get her off the track with false information in there."
As for how the family plans to celebrate the holidays, he says, "The main thing we know we're going to do is there's just gonna be nice family time and snuggles."
