Another season, another Housewives medical scandal! Lisa Rinna and Taylor Armstrong have questioned Yolanda Foster's Lyme disease diagnosis — as RadarOnline.com first reported — but now, one of her Real Housewives of Beverly Hills costars is speaking out to defend her.
"I think that is just a bunch of BS frankly," she told OK!. "I know for a fact that she is not faking it."
In fact, Davidson is having a hard time watching her friend go through all of her medical problems.
"It's really not easy," she said. "I care very deeply about her, and I see her struggling. Her cycle is really happening and it continues. It's hard to see your friend go through this kind of thing, especially in front of cameras."
Davidson admits she has never gone with Foster to see one of her specialists, however.
"I didn't go to the doctor with her," she said.
But she has stood by Foster's side through it all.
"I did see her a couple of times, probably more than that actually," Davidson said. "I think I've supported her in many different ways."
And while Davidson may not be on the best of terms with some of her other RHOBH costars, she does consider Foster to be "definitely a friend."
As Radar reported, Foster wasn't so lucky during Kyle Richards' recent season finale party.
After learning some of her pals were questioning her diagnosis, she got into a huge fight with them.
"The ladies seemed to think Yolanda had become a hypochondriac, or was making herself sick from undergoing so many alternative treatments," a source explained. "Yolanda was very, very upset and did indeed yell at them."
RHOBH premieres on Bravo at 9 PM ET on December 1.
