Is 'Vanderpump Rules' Jax Cheating On Brittany? Why Star Is Spiraling Out Of Control

Is Jax Taylor cheating on Brittany Cartwright?

The "Vanderpump Rules" couple already overcame one cheating scandal before their extravagant Kentucky wedding, which already aired during the current eighth season. Since then he's seemingly turned over a new leaf, but in a recent episode, Brittany becomes worried that her husband is reverting back to his old ways.

After Jax sabotaged his own pool party by sending obnoxious texts and uninviting guests, Tom Sandoval and Ariana Madix decide to throw their own bash at the same time with everyone welcome to stop by. Realizing that the 40-year-old former model ruined their event, Brittany expressed that "none of this would have happened" if he didn't lash out at everyone.

"I love that this is all my fault," Jax quipped. "I'm gonna go to the gym."

A trip to the gym seemed like a normal thing to do, however, it was the third time the "Vanderpump Rules" bad boy had pumped some iron that day which reminded his wife of that challenging time in their relationship when he was unfaithful.

"I feel like when Jax did cheat on me, I didn't see very much of him, or he would try to be gone from the house a lot," she revealed during an on-screen interview. "It just almost feels a little repetitive of things that we've been through in the past. I don't want it to ever get that bad again."

In late March, before the episode aired, the Kentucky native teased the drama that was to come ahead.

"Jax did go through, like, an after-wedding depression type-mode, where he was kind of spiraling for a minute, but it wasn't between me and him," she shared. "It was between him and his friends, so that's something people are gonna see … There was a couple, well, like two weeks, maybe, where Jax was very upset."

Although this "after-wedding depression" happened almost a year ago now, one relationship that still had not been repaired was between Jax and Sandoval, which Jax planned to address during the reunion.

"Vanderpump Rules" airs Tuesdays at 9 p.m. ET on Bravo.
