Kyle Richards Goes After Lisa Vanderpump More Than Once On 'RHOBH'

Although Vanderpump and her husband, Ken Todd, were invited to attend Brinson's memorial service earlier this month, they were unfortunately unable to attend. Still, things between the reality stars seem to be quite civil at this point.

"She's so lovely and the problems that she's kind of had, it's been very difficult for her, I would imagine," Vanderpump explained. "But you know what, really, I hate? It's now if I see the show and I see people being negative about her, I hate that."

While Vanderpump said she was "1,000 percent sure" Richards remains sober, the last few weeks have been understandably hard. Luckily, however, her family has been close by, and despite their ongoing turmoil amongst one another, both Kyle Richards and Kathy Hilton were in attendance during Brinson's funeral.
