Yolanda Foster Was the Real Star of Gigi Hadid’s 21st Birthday — As Ex David Foster Looked On

She gets it from her mama. Yolanda Foster was the real star of daughter Gigi Hadid’s celeb-filled 21st birthday bash at the Nice Guy in West Hollywood on Thursday, April 28.

The recently single Real Housewives of Beverly Hills star, 52, looked fierce in a lace paneled jacket and skinny black trousers as her estranged husband, David Foster, looked on.

Yolanda, who has been publicly battling Lyme disease — not to mention her critical RHOBH costars on the fiery reunion special — looked healthy and happy as she made her way into the hot spot.

Foster filed for divorce from David in January. During the RHOBH reunion special, Yolanda explained they simply grew apart and that her Lyme disease took a toll on her Grammy-winning ex.

"It didn't just happen overnight,” Yolanda explained during part one of the reunion on April 19. “I got sick a couple of months before we got married, and I dropped off the planet. Being chronically ill for that long takes the life out of you, but also your caretaker."

They’ve since remained amicable, however, and Yolanda has been vocal about David’s support.

“David and I are going to be great friends,” she said during the season 6 finale. “Just because the marriage didn't work anymore, it didn't change the fact that I still love him."
