Age is only a number – especially as far as Tom Cruise is concerned. Last month, the actor turned 48, but the father of three admits to having a secret for staying young.

“I love all my children, but Suri is my fountain of youth,” Cruise tells the German magazine Bild about his 4-year-old daughter with his adoring wife Katie Holmes. “We jump on the trampoline together.”

Cruise – also dad to Connor, 15, and Isabella, 17 – said he isn’t afraid to get older. “I’m still better than my kids at basketball,” he said. “One of these days, though, they’ll beat me and I’ll be delighted.”

So what did this man who has everything get for his birthday?

“For as long as I can remember, my mom has given me a roast chicken with green beans. Kate gave me The Great Escape [the classic 1963 WWII movie starring Steve McQueen]. The children gave me pictures, homemade videos and photos.”

And that, he said, is the gift that keeps on giving: “We paste everything into books, and when I page through them I am the happiest man in the world.”
