The pair made posts for each other on their respective Instagrams, and they offered followers a view of their relationship throughout the years. One of the best parts was that in Michael Douglas's post, he shared a photo from the night that they first met.
In the caption he wrote, “My first night meeting Catherine at the Deauville Film Festival in 1998. I found out that she had the same birthday as me--tadaah!”
The actor continued his message for her 52nd birthday, saying, “Then when I discovered she loved golf, I realized all my fantasies had come true. I've lucked out at this time in my life. I just lucked out. I'm so impressed by her intelligence, sense of humor and work ethic. Happy Birthday Catherine- I love you so much!”
