Catherine Zeta-Jones celebrates her 55th birthday in a real Adam costume – and calls it a gift for her husband Michael Douglas

Catherine Zeta-Jones is celebrating her 55th birthday in the bravest way possible: by baring it all.

The 55-year-old Welsh actress took to Instagram on Wednesday, September 25, to post a stunning black-and-white photo of herself wearing nothing but a pair of black heels. In the sultry image, she stands in a bathroom with tousled hair, her hands on the sink, looking at her reflection in the mirror.

“In my Adam costume! After sharing my birthday with my husband for over 25 years, I’m starting to run out of gift ideas! This is gift option two, golf balls are option one… of course,” she cheekily captioned the post.

Of course, there was a lot of excitement in the comments section and fans and celebrities alike applauded her.

Alec Baldwin joked, “That photo. No time for golf.” Another fan quipped, “Listen, if my body looks like that at her age, I’m going to post all the nudes and not care what you think.” One commenter even referenced her husband, Michael Douglas, writing, “Let’s face it, if Catherine looks like that NOW, every day is Michael’s birthday!”

Speaking of Douglas: The couple has the same birthday, although the age difference between them is 25 years. On his Instagram account Last Vegas Star posted a sweet clip of Zeta-Jones and Bono (yes, Bono from U2) singing Happy Birthday to him while holding a small round cake with an extra-large candle.

“What a beautiful gift! Thank you everyone for your lovely birthday wishes and messages! We love you all! @catherinezetajones @u2,” the 80-year-old actor captioned the post.

His comments were equally enthusiastic, with fans saying things like, “I want Bono to sing for me on my birthday!” and “What a beautiful video!”

Zeta-Jones and Douglas met in 1998 at the Deauville Film Festival in France. The couple, who married in 2000, are proud parents of 24-year-old son Dylan and 21-year-old daughter Carys. Douglas also has a 45-year-old son, Cameron, from his previous marriage to Diandra Luker.
