The 76-year-old, who is married to actor Catherine Zeta-Jones, told The Kelly Clarkson Show that his daughter Carys recently graduated from high school.
Michael Douglas has revealed that he was confused for his 18-year-old daughter’s grandfather at her graduation.
Douglas and Zeta-Jones have been married since 2000, after meeting at a film festival in France two years earlier.
“It was so wonderful, I’m so proud of her,” Douglas told Clarkson.
