In April, the couple celebrated their 27th wedding anniversary.
On Instagram, the X-Men star posted an image of the two on their wedding day.
“I love you Deb. Today is our 27th wedding anniversary. 27 YEARS!!” he wrote.
“Together we have created a beautiful family. And life. Your laughter, your spirit, generosity, humour, cheekiness, courage and loyalty is an incredible gift to me. I love you with all my heart.”
Before that, on Valentine's Day, Jackman had further showered praise on his spouse.
“Happy Valentine’s love. You light up the room wherever you go … your humour, generosity, wisdom and spirit shines so bright. I celebrate you on our 28th Valentine’s together. I (love) you.”
At the time, Jackman said the secret to his decades-long marriage was “honesty and intimacy and making time” is everything.
“You can’t just assume that things will just tick along OK. You have to make time,” he said on Smooth Rado in February.
“And intimacy is about really sharing what you’re going through, feelings, and checking in with the other person, checking in what they need from you, checking in, how they’re doing, checking and beyond.
“Just because it’s so easy to get caught up in the day-to-day of life. That’s hard enough. Kids, school runs, whatever it is, sleepless nights, it’s tiring. So you have to be checking in with each other.”
Jackman made another similarly loved-up social media post about Lee-Furness for their 26th anniversary last year.
“Today I celebrate 26 years of marriage to my extraordinary wife. Every single day is filled with so much laughter, joy and backgammon! Deb you light up my life,” he wrote.
“I love you with all my heart!”
The couple met on the set of the Australian prison drama Corelli in 1995 and were married the following year.
Lee-Furness had two miscarriages. In 2000, they adopted Oscar and in 2005 Ava.
In 2018, Jackman branded his wife and children “the greatest gift I will ever receive”.
“I believe in life we need to see and truly be seen by the most important people in our lives,” he said.
“Deb, from day one, we had that. 22 years later … it only gets deeper.”
