Supermodel Mama! Yolanda Foster, 52, Shows Off Smokin' Hot Bikini Bod

Yolanda Foster proved that her daughters inherited her supermodel genes by sharing a smokin' hot bikini pic on Instagram.

The "Real Housewives of Beverly Hills" star put her impressive physique on full display during her vacation in Tahiti, where she was snapped by the water in nothing but a red polka-dot two-piece.

"Happiness is the spiritual experience of living every minute with Love, Grace and Gratitude," the mother-of-three wrote, adding the hastags "Healing" and "#RainyDay in #Paradise."

The former model, who's been publicly battling Lyme disease for years, seems to be on the mend. She recently admitted that her kids -- Gigi, Bella and Anwar -- have helped her get through the toughest times.

"There were nights where Gigi, at three o'clock in the morning, had to drive me to the emergency room because I had such severe inflammation in my brain that I'd be balling on the floor like, 'Please take me to the hospital,'" Yolanda revealed on "The Dr. Oz Show" in March. "And not just Gigi driving, Anwar and Bella in the back of the car and the three of us going to the hospital. And, them being there, they learn to take charge and be my strength."

"There were many days that I really didn't want to live anymore," she added. "But when you look at your children it's not a choice anymore, right? You have to. You have to get through. You have to keep fighting and searching to get well."
