Lisa Rinna and Yolanda Foster were at odds recently on an episode of The Real Housewives of Beverly Hills, as they feuded over the health of Foster’s children, Anwar and Bella Hadid. On Wednesday that feud spilled over onto Twitter, with Foster taking the first swipe.

Lisa Rinna previously questioned Yolanda Foster’s Lyme disease diagnosis, and insinuated that her illness might be fake. Both Lisa Vanderpump and Kyle Richards had similar questions, but it was Lisa Rinna who took the fall for vocalizing the issue. RHOBH cast mate Erika Girardi spilled the beans about the doubters.

Yolanda Foster previously said talking about her kids was off-limits while on RHOBH. Lisa Rinna called her out on that as well.

Will this feud between Lisa Rinna and Yolanda Foster have the entire cast of RHOBH up in arms? Do you think Yolanda and her kids really are sick with Lyme disease or is there more here than meets the eye?
