When she joined the cast of Bravo’s The Real Housewives of Beverly Hills in the reality program’s third season, Yolanda Foster was expecting to have more than her share of trashy fun. But almost immediately thereafter, she was diagnosed with Lyme disease. “I had much more glamorous plans for myself, obviously,” she says with a resigned laugh. Instead, the former model parlayed her celebrity into a platform for greater awareness of the condition. She’s extended her campaign onto Instagram—a tool that’s been kind professionally to both Foster and her daughters, the ubiquitous models Gigi and Bella Hadid. “When I was modeling 30 years ago, we didn’t have that,” Foster says. “You went around with your portfolio, begging for jobs. Now, these kids establish themselves on social media and they just run with it.”
