Brittany Cartwright treated #stassi schroeder to a spa day in honor of her two-year anniversary with #jax taylor on Monday night's new episode of "#vanderpump rules." As fans saw last night, Cartwright seemingly leaned on Schroeder for support after Taylor admitted to cheating on her with Faith Stowers, and throughout their spa visit, they discussed his ongoing bad behavior.

Although the women's relationship is weird to some, Stassi Schroeder told The Daily Dish on December 19 that she went with Brittany Cartwright to the spa because they've become really close in recent years -- not because she dated Jax Taylor in the past.

As Schroeder explained, she also felt that Cartwright came to her for advice because Schroeder had been in her shoes in the past.

Stassi Schroeder was shocked to hear who Jax Taylor cheated with

Stassi Schroeder went on during her interview, telling The Daily Dish that she was shocked [VIDEO] to see Jax Taylor dip into their group of friends once again. As "Vanderpump Rules" viewers will recall, Taylor infamously admitted to cheating on Schroeder with their longtime friend Kristen Doute during the show's second season. Then, last week, he admitted to sleeping with Faith Stowers, who has been featured on the show for years, behind the back of his girlfriend.

Stassi Schroeder and Jax Taylor were dating when "Vanderpump Rules" began airing [VIDEO] on Bravo TV in January 2013. Then, after Taylor admitted to being unfaithful a number of times, Schroeder left him and began dating her now-ex-boyfriend Patrick Meagher.

Stassi Schroeder claims Brittany Cartwright and Faith Stowers were close

Although Faith Stowers has been on Instagram in recent weeks, claiming she and Brittany Cartwright were not friends in the months leading up to her affair with Taylor, Schroeder told a very different story to The Daily Dish. In fact, Schroeder claimed Stowers was a regular visitor at Taylor and Cartwright's Los Angeles apartment.

"[Faith Stowers] was spending a lot of time with [Brittany Cartwright] and Jax... like would go over to their apartment," Schroeder revealed. "That, I did not expect."
