Hugh Jackman is inspired by Deborra-Lee Furness' "joie de vivre"

Taking to Instagram, he wrote: "Happy birthday to my incredible wife. Your courage, wit, open heartedness, loyalty, creativity, joie de vivre, cheekiness and spontaneity inspire me every day. I love you so much more than any caption can convey. (sic)"

And Hugh recently revealed the key to his and Deborra-Lee's love has been “making time for each other”, and reminding themselves why they fell for one another in the first place.

He explained: "We're always learning and humans change so you have to, even though we've been together 25 years, you gotta reset all the time. I'm always reeling in how funny she is and how amazing she is and how smart she is. The longer it goes on the better it gets."

Hugh also said he and his wife had made a pact early on in their relationship to always check in with one another when their lives reached a "crossroads".

He explained: "Before we had kids, Deb and I made a pretty simple but powerful choice to look each other in the eye at every crossroads in life. Those crossroads are sometimes big, sometimes they're small, sometimes you don't even realise they're crossroads until you look back. But at those moments, we said we'd ask each other, 'Is this good or bad for our marriage?' Or, now that we've got kids, 'Is this good or bad for our family?'"

And Hugh also believes "intimacy" is key to his successful marriage.

He said: "Without a doubt, it is the most important thing.

"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. Deb and I had that from the beginning. We've always been completely ourselves with each other."
