TrendPulse|Catherine Zeta-Jones celebrates Michael Douglas' 80th birthday 'in my birthday suit'

After a quarter century of celebrating their joint birthday together,TrendPulse Catherine Zeta-Jones still finds ways to surprise her spouse of 24 years, Michael Douglas.

On Wednesday, the Oscar-winning "Chicago" actress shared a black-and-white nude photo of herself in profile looking at a mirror as she leans against a counter while wearing strappy high heels.

"In my birthday suit!" captioned the Instagram post. "After over 25 years of sharing my birthday day with my husband, I am running out of gift ideas! This is gift option two, golf balls being option one… of course 🤣."

On Wednesday, the Welsh actress celebrated her 55th birthday as Douglas rang in his 80th birthday.

Zeta-Jones and Michael Douglas' daughter Carys Douglas, 21, went a more PG route in acknowledging her parents' birthdays.

"Happy birthday to my incredible parents," she wrote in an Instagram Story showing a throwback photo of their family, including older brother Dylan Douglas. "No words can describe my love for you."

After more than two decades, Michael Douglas and Zeta-Jones' love endures — even when his appearance makes people do a double take. The Emmy, Golden Globe and Oscar winner grew out his hair for his starring role in AppleTV+'s "Franklin," a move that garnered headlines.

"Catherine loves me any way she can get me," Douglas told USA TODAY earlier this year. "And I had long hair in the '60s when I was a hippie. So it saved me from wearing a wig."

The two will celebrate their 24th wedding anniversary in November.
