Lisa Vanderpump Says ‘RHOBH’ Season 8 Tested Her Friendship With Kyle Richards (Exclusive)

The ‘Real Housewives of Beverly Hills’ star fills ET in on the “tumultuous” season to come, admitting she unexpectedly lost her cool.

It’s not all diamonds and rosè for Lisa Vanderpump this season on The Real Housewives of Beverly Hills, but it’s close.

“There was some stuff swirling around me, but I was ducking and diving,” she teases. “I didn't get myself into too much trouble.”

Lisa will seemingly be caught in the eye of the storm of season eight, but she's not the cause of said storm -- she calls the upcoming batch of episodes “tumultuous.” The trailer ends with Lisa driving away in tears, telling a shocked Kyle Richards and Dorit Kemsley that she’d rather be at home with her husband, who actually wants to spend time with her.

“Normally I have my cool, and I kind of lost it that day,” she says. “I think on Beverly Hills, you see this wonderful, glittering existence, and you also see the struggle that the women go through.”

“I was like, ‘OK, Alexis Carrington, got it.,’” Kyle recalls of the moment. “It was so out of character for her to let her guard down like that, that's why my mouth was literally hanging open.”

Still, Lisa notes that this year is nowhere near as bad as her roughest seasons, four and six.

“It’s normally the even numbers that aren’t good to me!” she says. “Eight was actually OK, so I’ve broken the mold.”

The restaurateur says the dynamic definitely changes this year, including a shift in her friendship with Kyle. She says things take a turn about halfway through the season, though the turn seemingly doesn’t cause any irreparable damage.

“You know, we have a great relationship, but like any relationship, it has its problems,” she shares. “Like any marriage, or you know, partnership in life or business, you have your struggles, but then you come through it. I think what we have supersedes, you know, the negativity.”

“I love Lisa,” Kyle says. “I mean, Lisa and I, obviously, we're very close. We're the closest of the bunch and I could never do the show without her. You know, we keep it fun.”

Lisa jokes that she doesn’t feel quite the same way about Kyle that Kyle feels about her.

“Not at all!” she says, with a laugh. “As soon as she's out of there, I'm gonna be front and center with a diamond.”

“I do think in some ways, we're very much the backbone of the show,” she continues. “We're the two existing [original cast members] and our friendship was always so strong, and it was so authentic. Even now, I call her up and I'm laughing and she's like, 'What are you laughing about?' and then we get to talking about something else.”
