Yolanda and David Foster are divorcing

Yolanda Foster is back on the market.

The “Real Housewives of Beverly Hills” star, 51, and record producer David Foster, 66, are calling it quits after four years of marriage.

“Sadly we have decided to go our separate ways,” the couple told People in a statement. “We’ve shared 9 beautiful and joyous years together. During that time we experienced love, friendship and the inevitable challenges that come with managing a marriage, careers, blended families and health issues.”

They continued, “We are grateful for the years we’ve spent together and believe wholeheartedly that we did our best. I hope that we can pave the road ahead of us with all we’ve learned and with the love and respect we will always have for one another.”

This is the fourth failed marriage for David, who has five daughters, and the second for Yolanda, who shares three children — Gigi, 20, Bella, 19, and Anwar, 16 — with her ex-husband Mohamed Hadid.

A month ago, Yolanda snapped a photo of herself and David celebrating his birthday at a Lakers game.

The couple wed in 2011. “Tonight, I’m the luckiest man on the planet,” David told his bride on their big day.

Yolanda’s rep did not immediately return a request for comment.
