It wasn’t all that long ago that Jax Taylor was swearing to Stassi Schroeder that he didn’t sleep with Kristen Doute, but it looks like the Vanderpump Rules star has been caught in yet another lie. When Stassi confronts Jax about the rumors in next week’s episode (Season 2, Episode 13), all the dirty details will finally be revealed.

“She slept with me, we slept together,” he admits over dinner with their friends. “Twice. Once as hers, once at mine. There’s nothing else I can do about it.”

Of course, being the master manipulator that she is, Stassi plans to use this information to destroy Kristen’s life. “I need your help,” she says to Jax. “I’m planning a get-together and Kristen is invited. I need you to be there. You know that when I do call her out, she’s gonna deny, deny. And when you are there and you’re telling her, ‘Yes, this is what happened,’ she’s gonna look at you and call you a liar. It’s time to tell the whole story. I’m going to destroy her. She’s going to lose every friend she has.”

Though Jax is clearly worried about his friendship with Kristen’s boyfriend, Tom, he vows to help Stassi with her plan. “I’m gonna do what you want with Kristen. I’m gonna do this for you because I respect you and I love you.”
