The legendary music producer said he's confident that his wife is "going to beat the disease."
In 2012, Real Housewives of Beverly Hills star Yolanda Foster was diagnosed with Lyme disease, and while accepting an award at the Global Lyme Alliance Gala in New York City on Thursday night, the former model was joined by her husband, legendary music producer David Foster, who praised her strength and courage.
"It's no secret that Yolanda's been sort of through the ringer the last four years," Foster said at the gala benefit. "Yolanda has brought a lot of awareness to the disease and here we are tonight."

Yolanda's presence at the gala was impressive in its own right, as Foster revealed that his wife hasn't been able to actually leave her bed in almost a year.
"She's going to beat the disease," David, 65, shared. "And when we see nights like this, it really gives us hope that we're going to nail it."
