Catherine Zeta-Jones put on her birthday suit in honor of her husband, Michael Douglas’ 80th birthday earlier this month.

Longtime New York resident actress Catherine Zeta-Jones found a new meaning for the term "birthday suit" in a new social media post. The 55-year-old actress posted a naked photo of herself on Instagram on Thursday, Sept. 25 to celebrate both her birthday and that of her husband, acclaimed actor Michael Douglas, who turned 80.

Catherine Zeta-Jones embraced her birthday suit in celebration of Michael Douglas’ 80th birthday on Wednesday. As a present to her husband of 24 years, the “Entrapment” star shared a revealing snapshot of herself on Instagram, which showed her leaning against a bathroom vanity with nothing on except a pair of sky-high heels.

On Thursday, Zeta-Jones posted a video that featured her and U2 vocalist Bono serenading Douglas with the “Happy Birthday” song as they held a dessert with a lit candle. The celebrity couple wed in 2000 and share two children together. Douglas also shares a son with his ex-wife, Diandra Luker.

The first post was a throwback black-and-white picture of them from the beginning of their relationship (they met in 1998). “Happy Birthday to Michael and to me!!” the Chicago star wrote in the caption. “This was us on our birthday 25 years ago! I love you with all my heart ♥️.”
