REPORT: Brittany Cartwright Began Hooking Up With Jax Taylor’s Friend Julian Sensley After Their Separation & Began Romance Before Jax “Went Beserk,” Plus See The Valley Star Step Out With Son Cruz

Brittany Cartwright is being accused of striking up a secret romance with her estranged husband Jax Taylor‘s friend, Julian Sensley, after their separation.

Days after Jax, 45, filed his second set of response documents to Brittany’s August divorce filing, Brittany’s alleged “casual” physical relationship with Julian, 42, a basketball player turned actor who once worked at TomTom, has been exposed.

According to an October 7 report from Page Six, Brittany, 35, and Julian began secretly hooking up with one another privately after she split from Jax, 45, earlier this year, but have since put an end to their short-lived romance.

The outlet went on to reveal that Julian, who was previously linked to Lala Kent, 34, is now engaged to the mother of his youngest, with whom he had been “off and on” prior to his fling with Brittany, which occurred during a “rough time” for the couple. 

As for how Jax reacted when he learned of his estranged wife’s romance with Julian, he reportedly “went berserk” and ultimately checked himself into a mental health treatment facility.

While Jax never publicly addressed the romance directly, he hinted at the relationship in a since-deleted post shared on X, formerly known as Twitter, earlier this year.

“You may want to ask Brittany who she’s been sleeping with for the past 4 months….” he wrote in his message.

As fans wait on the edge of their seats to see it all play out on the upcoming season of The Valley, Brittany is focused on her and Jax’s 3-year-old son, Cruz Michael Cauchi. And, earlier this week, she stepped out with the boy in Los Angeles.

Although Jax issued a response to Brittany’s request for divorce in September, checking a box that gave her full physical and legal custody of Cruz, he has since re-filed his documents, enlisting the help of the attorney of Britney Spears’ ex-husband, Kevin Federline, as he requested joint legal custody of the child.

The Valley season two is expected to premiere on Bravo sometime later this year or early next year.
