Lisa Vanderpump Shades Brandi Glanville on 'WWHL' -- And Brandi Barks Back on Twitter

Lisa Vanderpump still has an axe to grind with former friend and "Real Housewives of Beverly Hills" co-star Brandi Glanville.

On Monday's "Watch What Happens Live," a caller asked the restaurant mogul which "RHOBH" co-star she could never see herself being friends with again. LVP's had falling outs with a few different 'Wives over the years (Brandi, Lisa Rinna, consistent drama with Kyle Richards), but it seems the damage Brandi caused is irreversible.

"Well, 'never' is a big word, but Brandi Glanville," Lisa replied. Andy Cohen then asked LVP how she felt about Brandi's friendship with newcomer Denise Richards.

"Oh, I'm okay with that!" Lisa said, sounding quite genuine. "That's up to them. Everybody finds their own friendships. I have no problem with that whatsoever."

Brandi, who was clearly watching "WWHL," took to Twitter to respond to the earlier jab.

"What is it that I did that was so much worse than the others?" she tweeted at Andy. "Don't say [when I called you] Vandercunt cuz I called you that when we were still friends." Unfortunately for us viewers, Lisa didn't respond because the tweet wasn't brought up on the show.

Another caller asked Lisa about her "most embarrassing TV moment," which took the reality star a moment to think about. After some deliberation with Andy, Lisa recalled that infamous scene during the "RHOBH" trip to Amsterdam when Brandi slapped her in the face.

"I've had many moments I haven't liked," Lisa replied. "I didn't like getting slapped. I mean, that was just -- it shocked me. The whole physicality of it, it just felt so invasive."

Brandi replied to that comment as well.

"That was a love tap," she tweeted. "I never meant to physically hurt you. It was 'puppy play.'" Again, no response from LVP.

Lisa also talked "Vanderpump Rules" drama and defended James Kennedy amid his very rough start to Season 7.

Former SURver Kristen Doute was also clearly watching "WWHL" and also tweeted at Andy, who read the message to Lisa during the show.

"Oh, c'mon, Lisa -- you're better than that to blame editing. James thinks Raquel is dumb. It doesn't mean he's right or wrong," Kristen wrote.

"You know what? Let's not hit somebody when they're down, okay?" Lisa fired back at Kristen. "Because I even saw her [on 'Vanderpump Rules'] tonight, saying, 'Oh, he hasn't drunk for a week and a half.' When was the last time you didn't drink for a week-and-a-half?"

Lisa shaded Kristen once more when a caller asked if she'd rather re-hire Kristen or hire James' girlfriend, Raquel Leviss, as a SURver. LVP didn't even have to think twice.

"Well, Kristen was a good server, I have to say that. But Raquel," she said with a smile.
