In the wake of wife Yolanda Foster’s Lyme disease diagnosis, David Foster has acted as a pillar of support. The “Real Housewives of Beverly Hills” star’s husband is speaking out about Yolanda’s diagnosis, calling her “a fighter.”

David recently told E! News his wife’s “got big balls” for the way she’s handling her diagnosis. He said it’s been a long three years since she learned she had the disease, but she has yet to give up. The Grammy Award winning musician told the site Yolanda is currently doing alright and continues to try to lead a normal life despite the side effects of her condition. The 65-year-old added that he has been doing his best not to let her condition get him down.

“This isn’t happening to me. It’s happening to her, and if the situation were reversed, I want to try to be, for her, the person that I would want her to be if I got sick,” he said. “She will get through it. For sure.”

Yolanda has struggled very publicly with her disease, speaking openly about her quest for a cure. A recent post on Instagram disclosed to fans that, while she had been on a path toward good health, a relapse in December had caused her to lose the ability to read, write and take in stimuli. In early May the “RHOBH” star revealed that she had decided to forego Western medical treatment in favor of a more holistic approach.  Yolanda has flown to Germany, Mexico and Singapore to receive different kinds of treatments not offered in the United States.

It has not been announced if, given her poor condition, Yolanda will be returning to “The Real Housewives of Beverly Hills.” Filming for Season 6 has, however, officially begun.
