'RHOBH' Recap: Lisa Bails on Camille's Wedding to Avoid Awkward Run-Ins with 'The Real Bitches of Beverly Hills'

Lisa Vanderpump didn't just bail on Camille Grammer's bridal shower, she was also absent from her big day.

Tuesday's new episode of "The Real Housewives of Beverly Hills" documented Kyle Richards, Lisa Rinna, Dorit Kemsley and Teddi Mellencamp dancing their you-know-whats off at Erika Jayne's first show of her Pretty Mess Tour. With the exception of a technical malfunction, Erika nailed it, and Mr. Girardi could not have been more proud.

Denise Richards couldn't go because she was heading to Miami to film for a TV show. She was distraught having to leave the night of daughter Sammi's homecoming dance, but she did get to see her right before it was time to put on her dress. Still, the emotions of being a working parent took over, and Denise left for the airport in tears.

It's unclear why Camille was absent from Erika's big night, but it's very clear why Vanderpump was. She hasn't gotten along with any of the girls since her big blowup with Kyle over accusations she leaked PuppyGate-related stories to the press. Although Camille seemed to be the only person in LVP's corner, she was still unsure if she'd come to her wedding, so she stopped by Villa Rosa to have a chat.

Joking about Camille's massive engagement ring and the old saying, "Diamonds are a girls best friend," LVP said that diamonds are sometimes "better friends than your friends."

"You know, those girls can be..." Camille trailed off as LVP interjected, "Yeah. They've been horrible. Horrible. And I don't want to include you in that at all. Not at all."

"If you were to come to my wedding -- which, you know that I would love for you to be there -- I would want you to feel comfortable within the group," Camille said. "Of course I want you there, so will you come?"

After a brief pause, Lisa said she had to decline.

"I've always cared about you, you know that," she said solemnly. "I just -- I can't make the wedding."

Camille was visibly disappointed but said she understood Lisa's predicament because she would hate for her to feel "all this pressure from the ladies" at an event that should be joyous for everyone.

"Well, you can invite me and cancel everyone else!" Lisa half-joked, half-suggested.

"As much as I want to see Camille get married, I'm not gonna put myself in that situation with them all against me," she later vented in a confessional. "Let the Real Bitches of Beverly Hills go on their own."

To Lisa's joke, Camille let out a courteous laugh and replied, "I wish there was a way I can help make this better, but I don't know how to. I care about you and Kyle. We've been around each other for a long time. And there's some girls that I'm still getting used to that are still new to the group..."

"You're upset with the girls? What do you mean?" LVP quickly asked. Camille filled her in on her tiff with "know-it-all" Teddi, who she feels doesn't always understand the complexity of the ladies' relationships because she's still kind of new to the group.

"There's a lot of love between you and a lot of these girls," Camille insisted. "Especially Kyle."

LVP said she felt her co-stars were set on trying to make her feel like a "terrible person" and that her definition of friendship didn't include not believing someone when they say they're telling the truth.

"What am I supposed to do? Take a lie-detector test? Is that what they want me to do?" she asked. (Hold this thought.)

While careful not to come across as Team Kyle, Camille told Lisa she saw "sadness" in Kyle over her fallen friendship with LVP and that she believed Kyle really missed her. But Lisa wasn't really interested in hearing about her former friend's emotional state.

"How she was when she came around here when she said, 'I believe them and I don't believe you're a good friend and I believe you're more concerned about your image than your friends,' I was just like, 'You might as well have hit me around the face,'" Lisa said. "And I was like, 'Get out,' but I also actually meant, 'Get out of my life.'"

"I've been there," Camille later told the camera. "I've had to sit there and have people call me delusional, a liar -- and maybe I have more strength than she has because she runs away from it."

"Lisa's never been a victim," she added. "She doesn't live her life like a victim, but she's behaving like she is one. It's sad to see. This is not the Lisa that I knew. The Lisa that I knew would show up. What she's doing is she's running from everybody. It's almost like this immature girl hiding from the truth. Lisa Vanderpump talks the talk, but I wanna see her walk the walk."

Camille tried quite hard to remind Lisa just how solid her friendship with Kyle once was, but the attempts fell on deaf ears.

"I think Kyle Richards just enjoyed throwing me under the bus a little too much, and unless she changed her position and apologized, I've got no intention of seeing her again," Lisa told the camera.

But back to that part about the lie-detector test! The preview for next week shows Lisa taking a lie-detector test 24 hours after her visit with Camille. She's accompanied by her Vanderpump Dogs confidant, John Sessa, and nervously hooked up to the machine.

"Have you ever given a story to Radar Online?" the administrator asks. Lisa replies, "This is quite tight, this blood pressure thing, isn't it?"

More on that next week.

"The Real Housewives of Beverly Hills" airs Tuesdays at 9 p.m. on Bravo.
