Richards and Umansky share three daughters — Alexia, 25, Sophia, 21, and Portia, 13. (Richards also has a daughter, Farrah, 32, from her first marriage.) In January, the longtime couple celebrated their 25th wedding anniversary.

"25 years ago today we said 'I do' We have built a life together that I am so proud of," Richards captioned a series of throwback pics in honor of the milestone anniversary. "Our family is my greatest accomplishment. I still get happy when I hear your car pull in the driveway and still get sad if we have to spend a night apart. How is that even possible?? May we continue to grow, learn, explore, experience & create incredible memories side by side. I love you forever ❤️ #25years #silveranniversary."

Umansky, 51, wrote in his own post, "They say you need a little luck in life. Well the day I met my wife was the luckiest day of my life. Now 25 years later I am still the luckiest man on earth to have @kylerichards18 as my companion in this life journey."

"We're best friends," added Umansky. "We actually enjoy each other. She's funny, she makes me laugh. I don't have big guys nights out; Kyle is the person I want to spend most of my time with."
