The actor opens up about the secret to his long lasting relationship

Hugh Jackman, 50, will be celebrating his 23rd wedding anniversary with wife Deborra-Lee Furness, 63, on April 11 and says the secret to their long lasting relationship is honesty.

“Without a doubt, it is the most important thing,” Jackman tells PEOPLE in this week’s issue.

The 50-year-old Aussie, who voices an explorer in the animated movie Missing Link and will be headlining his first world tour, The Man. The Music. The Show., in May, says he and Furness had that important ingredient from the very beginning.

“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,” says Jackman. “Deb and I had that from the beginning. We’ve always been completely ourselves with each other.”

The couple met on the set of the Australian drama Corelli in 1995 and have two kids together, Oscar, 18, and Ava, 13. Jackman says family time is always a top priority for him.

“Going to our country house, lighting a fire at night and roasting marshmallows is my favorite thing to do,” says Jackman.
