Tom Cruise has revealed that he has a 'special' treat in store for wife Katie Holmes' birthday.

The actress turns 30 on Thursday and Tom has arranged his promotional schedule for new movie Valkyrie around his wife's big day.

“We’re gonna celebrate, I’ll be here (in New York) in the morning with her,” he told Access Hollywood.

But the actor was keeping tight-lipped about the exact details of his birthday surprise – but it sounds like he has something suitably spectacular lined up.

“I’ve got some special things...that I have in store for her,” he added.

“It’s gonna be a great day for her.”

Intriguing!
