Katie Holmes KatieBDay01B.jpgToday is Katie's 30th Birthday!!

A few days ago, Tom said he and Katie have been celebrating all week and he's got something special planned for her big day.

But Cruise and Holmes will have to celebrate early today, because Tom’s heading to the Los Angeles premiere of “Valkyrie” tonight, while Holmes will remain in New York for a performance of her hit Broadway play, All My Sons.

What kind of surprise do you think Tom has in store for Katie's B-Day?
