"7 years ago today, I said ‘I do’ to my best friend and father of our two and a half month old son. Thought it could never get better than that day, but it did. Happy anniversary darling, Michael. With you, in my life, and Dylan and Carys, every day could be a twelve hour fantastic party at the Plaza in New York. Love you. #love #lovestrong"
The happy couple share two children together, 17-year-old Dylan Michael Douglas and 14-year-old Carys Zeta Douglas.
Catherine shares the occasional family photo on social media, showing how quick her children are turning into adults. Take a peek at some of their sweet family moments below:
