Catherine Zeta-Jones, Michael Douglas, and their son Dylan came together to celebrate a special milestone as their daughter, Carys Douglas, turned 23, with the family marking the occasion through affectionate public tributes and nostalgic throwback photos.

On Monday, April 20, Carys celebrated her birthday, prompting heartfelt posts from her famous family across social media. The actress and Michael Douglas, who have been married since 2000, also share son Dylan, 25, while Douglas is additionally father to Cameron, 47, from a previous relationship.

To honor his daughter, Michael Douglas, 81, posted a photo of the pair from a recent appearance at the PAC NYC Icons of Culture Gala in New York. Alongside the image, he shared a warm message wishing Carys happiness and inspiration in the year ahead, closing his caption with a loving note signed “dad.” The post quickly drew affectionate responses from fans, who praised both the family bond and Carys’ striking resemblance to her parents.
Catherine also joined in the celebration, sharing a series of personal family photos that included sweet images of Carys as a young child. Her message expressed love and admiration, wishing her daughter a joyful and meaningful year ahead.

Dylan Douglas added his own tribute, posting a collection of childhood pictures of the siblings together. In his caption, he reflected on growing up alongside his sister, calling her his “built-in best friend” and celebrating the bond they have shared since childhood. Carys responded warmly in the comments, echoing the affection with a simple message of love.

Now 23, Carys is carving out her own path. She recently graduated from Brown University’s Watson Institute for International and Public Affairs, following in her brother Dylan’s academic footsteps.

Raised between multiple homes—including Bermuda, New York, and Spain—the Douglas siblings grew up within a globally rooted family background tied to both Hollywood and international heritage. Despite their high-profile upbringing, the family has often emphasized strong personal connections and close-knit traditions, which were clearly on display during Carys’ birthday celebration.
