Sex and the City star Blair Underwood and his wife of 27 years, Désirée DaCosta, are going their separate ways.

The 56-year-old actor and DaCosta announced their decision on Sunday via a joint statement posted to social media. The now-estranged couple shares three children: 24-year-old son Paris, 22-year-old daughter Brielle, and 19-year-old son Blake.

"After a tremendous amount of thought, prayer & work on ourselves individually & collectively, we have come to the conclusion to end our marriage that began 27 years ago," they began their statement.

"It has truly been a beautiful journey," they went on. "Our proudest achievements are our three incredible children. Three souls to which God entrusted us. We continue to be awed & humbled by the blessings of parenting. We have always put their best interests first & will continue to do so. We will continue to be the best of friends and co-parents and have the utmost respect for one another as we embark upon this new chapter of our lives, separately."

The now-exes concluded their announcement with gratitude, telling their family friends and fans, "We thank you all for your support throughout the years & we humbly ask for privacy & understanding during this new season of change."
