Cook took to Instagram to celebrate National Daughters Day and posted a photo of Sailor from Dancing With The Stars.

“Happy belated national daughters day! I’m proud of the courage and skill my daughter has demonstrated on dancing with the stars! XOXO,” Cook wrote.

This will be Cook’s third marriage. He was married to model Brinkley, 65, from 1996 to 2008. Cook was then remarried to Suzanne Shaw, 38, and the pair split in 2014.
