jax taylor and Brittany Cartwright's relationship comes under fire in the sixth season of "Vanderpump Rules." As fans saw during last week's episode of the show, longtime guest star Faith Stowers accused Taylor of cheating on Cartwright with her several months ago, prior to the start of production on the new season in May.

While Taylor has been known to cheat in the past, the reality star and bartender, at SUR Restaurant, quickly shot down Faith Stowers' allegations as false as his girlfriend [VIDEO], Cartwright, appeared to be skeptical.

After learning of the rumor, Cartwright immediately took aim at Jax Taylor, telling him that if the report was proven true, she would promptly move out of their home — and take their two dogs with her.

Faith Stowers is speaking out on Instagram

During the debut episode of the sixth season of "Vanderpump Rules" last week, fans didn't see too much of Faith Stowers. Although she was seen chatting with James Kennedy and his girlfriend, Raquel Leviss, she left Scheana Marie's birthday party shortly after word got out of her alleged hookup with Jax Taylor. Months later, Stowers weighed in on her drama with the cast and the hate she's received on Instagram.

“People are really coming for me but I learned a valuable lesson,” she wrote days ago in the caption of a video post on her page. Faith Stowers also told another fan that people don't really know what happened between her and Jax Taylor and will continue to have their own opinions until they "see the truth."
