RHOBH Flashback Catfight: Lisa Rinna Calls Kim Richards Sick

Enemies are formed on The Real Housewives of Beverly Hills each and every season, but no one will ever forget Lisa Rinna and her feud with Kim Richards.

In this flashback video from the Season 7 reunion, Rinna decides to lay into Richards after a rough season together of fighting and insults — and she certainly doesn’t hold anything back.

“I think you’re a really sick woman. I’m sorry, I think you’re a sick woman. To do something like that is sick,” Rinna says. Richards then adds, “Well I’m sorry you feel that way because I feel the same way about you.” Watch the clip above to see how all of the drama goes down!
