Awkward alert.

ET has your exclusive first look at Monday night’s all-new episode of Vanderpump Rules, which finds the SUR-vers hanging out at a Vanderpump Dog Foundation event. After hanging out with some dogs, Stassi Schroeder and Kristen Doute decide to pay their former boss, Lisa Vanderpump, a visit.

EXCLUSIVE: A Day in the Life of Stassi Schroeder

“Here comes trouble,” Lisa says to her former Real Housewives co-star, Joyce Giraud de Ohoven, as Stassi and Kristen approach her. “I might need backup.”

“Under any other circumstance, I’d be pissing myself thinking about having to go and talk to Lisa,” Stassi admits. “There’s no way Lisa could be mean to me. I’m disarming her… with my pups.”

“We just wanted to come over and say, this is, like, the coolest thing anyone has ever done,” Stassi congratulates. “I’m so proud to know you.”

“You’re saying something good and positive?” Lisa replies, before asking for a donation for the foundation. The girls say they’ve already given some money, to which Lisa has an interesting response.

“I think you’ve been giving some people more than what they need, from what I hear,” she says to Kristen.

Lisa is, of course, referencing the rumor that Kristen hooked up with Jax Taylor’s girlfriend, Brittany Cartwright. On the season premiere, Jax claimed he walked in on the two having an intimate moment together.

“Kristen is a squirmer,” Lisa snarks in a confessional. “I love to see her squirm! I cannot resist a little dig in her direction.”

“I’m speechless,” Kristen says. “I have no words. Jax is a f**king a**hole.”
