VPR Reunion: Ariana Faces Off with Lala After Failing to Respect Her 'Boundaries' with Sandoval Post-Affair

"She had very solid boundaries of what she was comfortable with and what she wasn't and I have mine… I supported yours. All you have to do is say I respect yours," Ariana Madix told Lala Kent

Ariana Madix is drawing a line in the sand when it comes to her “boundaries” with ex Tom Sandoval.

On the second part of the Vanderpump Rules reunion that aired Tuesday, May 21, host Andy Cohen asked the Dancing with the Stars alum, 38, how she felt about Scheana Shay remaining in touch with Sandoval, 41, after his headline-making affair with Rachel "Raquel" Leviss.

“Your feelings are totally valid,” Ariana told Scheana, 39. “Obviously, I'm not necessarily the person to go to with those feelings.”

However, Scheana vowed that she would always be team Ariana, saying, “I just wanted her to know you're still my girl, understand that I'm still here. Even though I'm in Tahoe on this trip, I'm still here. And I think a lot of times my tone and the way I speak I tend to misspeak and say the wrong thing to the wrong audience.”

Lala Kent admitted that she struggled with why Ariana needed to set firm boundaries within the friend group despite her doing the same with her ex Randall Emmett, with whom she shares daughter Ocean Kent Emmett.

“There's one giant difference. I have a child involved that I entered a custody battle… My ex did not call Schwartz over because he likes to hang out with Tom Schwartz,” she said of her ex. “There was a motive there and I was fighting for the well-being of my child and unless you have a child and you’ve been in my situation, you will never understand it.”

When Katie Maloney noted that Ariana should be allowed to have boundaries too, Lala responded, “This is where I get confused because there's a boundary that's happening, but she's sleeping down the hall from him and has a new boyfriend.” 

Ariana then brought up Katie’s divorce from Tom Schwartz, asking, “Was there an issue when Katie was dating after her divorce?” 

Ariana continued, “She had very solid boundaries of what she was comfortable with and what she wasn't and I have mine… I supported yours. All you have to do is say I respect yours. That's it.” 

As continued to argue over Lala not honoring Ariana’s boundaries, Ariana finally snapped. "The way you’re talking right now is not very respectful," she said. "You’re not being very respectful.”

Finally, Ariana told her costar, “I’ve always known your situation is different and I’ve always f---ing supported that.”

The argument concluded with Ariana saying, “You’re louder than everyone so you’re right” and Lala replied, “I have not raised my voice, not once.”
