Kyle RichardsandLisa Vanderpump‘s friendship hasn’t recovered from their rocky season ofThe Real Housewives of Beverly Hills.

During a Thursday night appearance onWatch What Happens Live with Andy Cohen, Richards said she hasn’t spoken to Vanderpump or her husband Ken Todd since a blowup at their house while filming season 9.

“The last time I spoke with Lisa or Ken was when I was at their house and we were going to have a talk, and then it ended up being a disaster,” she said. “When you’re kicked out of someone’s house … it was really strange for me because I’m so close with them.”

Richards, 50, said any attempts to contact Vanderpump, 58, have gone unanswered.
