Is 'Vanderpump Rules' Star Stassi Schroeder Cutting Katie Maloney Out Of Her Life?

After being confronted with allegations of disposing of friends after she shunned her former best friend Katie Maloney, Schroeder lost her cool, slamming Vanderpump for siding with those who work as her puppets.

"You're not listening to anything, and you're just going to hear whoever is willing to do what you want and it's not okay," Schroeder fumed. "It's not okay! That is what you do!"

Is Stassi Schroeder Quitting 'Vanderpump Rules' After Season 3?

When Vanderpump Rules first began, Vanderpump and Schroeder were close, but after Schroeder ditched SUR after season two, their relationship became strained. Although Schroeder claimed to have quit working at the restaurant before moving to New York City last summer, Vanderpump felt she left without a proper "goodbye."

While Schroeder continues to be seen on the show, she's no longer working at SUR, and doesn't have much of a relationship with any of her co-stars.

In an interview after the SUR scene was shot, Vanderpump explained her issues with Schroeder.

"The thing that bothers me about Stassi is she's not really looking for friends, she's looking for followers," Vanderpump explained. "I don't understand it. The fact that she storms off from the table just goes to prove the point that she doesn't have an argument."
