Catherine Zeta-Jones shares sweet throwback video of daughter Carys on her birthday

Catherine Zeta-Jones is celebrating her daughter on her birthday.

On Thursday, the "Wednesday" star shared a sweet throwback video of her daughter Carys Zeta Douglas from when she was a young girl. In it, Douglas shows off her tap-dance moves to Zeta-Jones, who is filming the video as they spend time on a dock overlooking a lake.

The video includes another throwback photo of the mother-daughter duo and an image that explains the meaning of the name Carys.

"A Welsh feminine given name derived from the word caru, 'to love,'" a slide included in the video reads.

In the caption of the video, Zeta-Jones wrote, "Twenty years ago today my daughter Carys came in to my arms and there is not a day I haven't cherished. Happy birthday beautiful lady."

Zeta-Jones shares her daughter with husband Michael Douglas. The couple also have a son together, Dylan Michael Douglas, 22.
