"Right now we're OK," Richards told Haute Living Tuesday. "We're a work in progress." Richards admitted that their past hasn't been easy, despite being friends at one point. "There are a lot of feelings that have been hurt. In the past, I've felt that, and she's felt that. We have a lot of working through things, but we're OK."

Richards continued, "[The situation with Lisa] is stressful, and I don't need any more stress in my life -- I sent my daughter off to college today. It's been torture." Richards recently sent her daughter Alexia off for her freshman year of college at University of Arizona. Richards even posted on Facebook a family photo of everyone waiting for Alexia.

Richards also told the magazine about how it feels to have new ladies Lisa Rinna and Eileen Davidson as part of the Real Housewives cast.

"I've been friends with these two women; one more than the other," Richards shared. "It's interesting to see because it's not easy for them coming into this environment with all of us that have gone through so much together." Richards also said that the cast is still dealing with issues from last season, as well.

Real Housewives of Beverly Hills is expected to come back this fall.
