Stassi Schroeder Isn’t Pleased by Scheana Marie’s Response to Her Hamptons Invite in ‘Vanderpump Rules’ Sneak Peek

More the merrier? A lunch at Sur between Stassi Schroeder and her New York-based twin pals Ashley and Lauren Wirkus sparks discussion of a getaway to Montauk, New York, on Vanderpump Rules’ Monday, December 12, episode, as seen in Us Weekly's exclusive sneak peek.

In the Bravo series' preview clip, Lauren — who, along with her sister, is on the cast of the network's upcoming series Summer House, launching Monday, January 16 — tells Schroeder about her plans. “Our best friend's getting married, then we start this summer in the Hamptons," Lauren reveals. "Have you ever been up to Montauk?"

Schroeder answers, “So you know I lived in New York, but it was six months during the winter.” She continues, “But I have always wanted to go to the Hamptons, and I have never got to do that. It’s been something I’ve wanted to do since I was a kid.”

Lauren tells her about Montauk, “We are making sure we are leaving our trip early so we can be there for the first weekend. Like, I’m not missing the first weekend."

Schroeder is delighted when she learns that the ladies will be there for her birthday on June 24. This leads Lauren to say, “Well, if you’ve never been, you should definitely make a girls trip and come.”

Taking a break from work, Scheana Marie and Katie Maloney join the girls. Schroeder chimes in with, “I have a really fun proposal. I want to do a birthday trip in Montauk." But a confused Marie asks, "In where?"

“Like, really?” Schroeder gripes to the cameras, clearly annoyed at her frenemy's question.

Marie dishes in a testimonial, “I’ve never been to the Hamptons. My vision of it has always just been this, like, rich beach that all New Yorkers go to in the summer every weekend. I just didn’t grow up like that.” In a mocking tone, she continues, “Your house in the Hamptons, and you’re so cool.”

Watch the clip above to find out whether or not Marie joins the ladies at the beach. Vanderpump Rules airs on Bravo Mondays at 9 p.m. ET. Summer House launches on Bravo Monday, January 16, at 10 p.m. PT.
