Michael Douglas and Catherine Zeta-Jones have been proud parents on social media this week.

The married couple of 20 years share two children together, daughter Carys, 18, and son Dylan, 20. This week, Carys graduated high school, and her famous parents couldn't contain their excitement about the achievement.

Both Douglas, 76, and Zeta-Jones, 51, honoured their daughter's milestone with photos and tribute messages on their Instagram pages.

Zeta-Jones sweetly wrote: "Carys!!! What a proud day as our daughter Carys graduates with honors for her International Baccalaureate! You rock and we love you."

Both Zeta-Jones and Douglas shared the same pictures on Instagram, one of the family of four happily posing together, and the other of the siblings celebrating Carys's big day.

On his post, Douglas wrote to his daughter: "Congratulations to Carys and the entire class of 2021! Your Mom and I are so proud of you! We love you so much and we are so excited for your future as the best is yet to come!"

Carys Zeta Douglas, the new grad, is the youngest of Michael Douglas's three children, one of whom was born to the actor in his first marriage to Diandra Luker. Carys and Dylan's half-brother, Cameron Douglas, is in his 40s today.
