Lisa Vanderpump Gets Defensive Over Yolanda Foster Lyme Disease Doubts

Real Housewives of Beverly Hills star Lisa Vanderpump went to bat for herself this week, defending her doubts over Yolanda Foster's Lyme disease diagnosis.

"I had questions, but I think you see she has questions too," the reality star star shared on SiriusXM's Dirty, Sexy, Funny with Jenny McCarthy on Tuesday.

"She's having her breast implants taken out, so is it silicone poisoning that is really damaged her immune system? She's had amalgam taken out of her mouth, she added, suggesting that there could be more to the story than just Lyme disease.

When it came to the surprising news of Foster's divorce, Vanderpump says she was "totally gobsmacked, an English word meaning shocked.

The Vanderpump Rules star isn't alone in her doubts of Foster's illness, however, as costars Kyle Richards and Taylor Armstrong have also voiced concern over the former model's "dramatic" antics.

"I think a lot of it has to do with questioning the types of treatments and the lengths she was going to, Richards said on HuffPost Live in early December. "She was going off to Korea and Germany and Mexico and all these cockamamie treatments.

Meanwhile, Foster continues to take the high road when it comes to her haters, though she recently slammed her RHOBH costars for being " ignorant about Lyme disease.
