Has Denise Richards' Friendship with Brandi Glanville Impacted Her Relationship with Lisa Vanderpump?

During Season 9, Lisa Vanderpump gradually became estranged from all of The Real Housewives of Beverly Hills ladies, except one: Denise Richards. The actress and RHOBH newbie was the only cast member invited to Lisa's birthday party, after all. But Denise also filmed this season with her friend Brandi Glanville, who appeared on RHOBH from seasons 2 through 6. Brandi and Lisa were once close but famously had a falling-out and are not friends today.  o when Denise came on Watch What Happens Live with Andy Cohen, she shared whether filming with Lisa's onetime bestie had caused a rift in their friendship (clip above).

"I actually have no idea if me meeting Brandi rocked the boat," Denise admitted. "I was just getting to know Lisa Vanderpump prior to her not wanting to be around any of us but if she ever extended an invitation to show up to one of her events or anything like that, I would obviously support her, because I believe in a lot of stuff that she supports so I would be there for her."

Lisa recently shared that she was leaving RHOBH after nine seasons. She told Extra, “The last year was a very negative year for me. I feel like we’re moving forward. They have had their resolution," she shared. "I just had a horrible time with the show and the women. It was a very sad time in my life and it wasn’t made any better. I just decided to walk away.”
