It’s Hugh Jackman and Deborra-Lee Furness.

“Happy anniversary #mydebs #23,” the 50-year-old actor captioned this funny throwback of himself and his actress wife, 63.

This week, Jackman also told People that the secret to a long marriage was “intimacy.”

“Without a doubt, it is the most important thing,” he told the mag. “People talk about intimacy and assume that means in the bedroom. Of course it is that, but really, intimacy is being able to share everything together — good, bad, fears, successes.”

And, evidently, chocolate cake!
