Mauricio Umansky is sending well wishes to the birthday girl.
On Thursday, the Agency CEO shared a throwback video of his estranged wife, Kyle Richards, dancing on a stage to the tune of Carly Rae Jepsen’s hit song “Call Me Maybe.”
“Wishing you a very Happy Birthday @kylerichards18,” he wrote atop the clip, which the “Real Housewives of Beverly Hills” star reposted on her Instagram Stories.
Richards, who turned 55 Thursday, kicked off her birthday festivities with a trip to Punta Mita, Mexico, this week with her close pal Morgan Wade and some other friends.
However, Umanksy was nowhere in sight.
In photos obtained by Page Six, the “Halloween Ends” actress and her friends had some fun in the sun as they enjoyed a nice beach day.
She sported a black-and-white bikini and a straw cowboy hat, while the country musician wore black board shorts and a white Gold’s Gym tank top with a bikini top underneath.
Wade, 29, also rocked a black baseball cap.
In July, Page Six confirmed that Umansky and Richards — who tied the knot in January 1996 — had separated after 27 years of marriage.
Though the real estate broker confirmed in September that he and the reality star were spending time apart, he later recanted, telling Page Six that their marriage wasn’t completely over.

“We’re struggling. We’ve been very open about it,” he told us in October during his stint on “Dancing With the Stars.”
“We’re separated [but] we’re not throwing in the towel yet.”
Fans are convinced that Richards has since moved on with Wade, whom she has been spending a lot of quality time with.
In fact, the pair even have matching tattoos and jewelry together.
However, the “Halloween Kills” star denied that they were anything more than friends.
Despite Umanksy and Richards’ separation, they have remained amicable for the sake of their three daughters, Alexia, Sophia and Portia, plus the Bravolebrity’s oldest child, Farrah, from her previous marriage to Guraish Aldjufrie.
Last month, the family hit the slopes in Aspen, Colo., while spending quality time together for Christmas.
