AceShowbiz - The feud between exes Jax Taylor and his estranged wife Brittany Cartwright only escalates day by day. On Wednesday, June 5, Jax took to his social media account to make a rather wild allegation against his ex.

"You may want to ask brittany who she's been sleeping with for the past 4 months….," so Jax wrote on his X account. "The Valley" star quickly deleted the post, but not before Internet sleuths took screencaptures of his tweet.

In response to Jax's post, some Internet users trolled him. Blasting the "Vanderpump Rules" alum, one wrote, "I truly hope he's the hottest MF on this planet. Good for her. You really think you did something here @mrjaxtaylor." Another said, "Thank GAWD it's not you!"

"Not a single person looks at your situation and doesn't recognize the problem. You need to find some self awareness," someone else suggested. Meanwhile, another critic added, "Why would you be treating your wife and mother of your son like this on a public forum? Do fame and TV mean that much to you to air your dirty laundry for all the world to see? Disgusting."

Jax's tweet came after Brittany revealed her last straw that led to her split from Jax in "The Valley" season one finale. The June 4 episode saw the exes having a heated conversation following their separation in which Brittany told Jax, "You're not just gonna get away with the way you've treated me for all these years."

In a flashback scene, the Kentucky native discussed all the insults that Jax has hurled at her over the years with co-stars Kristen Doute and Zack Whickham. "Does he say, 'I know I treat you like s**t,' " Kristen asked. " 'I know I'm mean. I know I've called you fat and I've told you you're f**king lazy and that you're not going to have any friends if you guys break up?' "

Brittany admitted, "That was one of the main things, him saying I have no friends here in L.A." She also called out Jax who told her he would seek help for his anger problems. "The day before we pick cameras back up, he all of a sudden has an appointment to go see the doctor. This is all a front. This is what he wants everyone to see and believe that he's actually gonna do these things to change. I bet you money he will not do it," she said in confessional.

Brittany, who shares 3-year-old son Cruz with Jax, announced her separation from Jax in February, after almost five years of marriage. "Marriages in general are very hard, and I've had a particularly rough year this past year," she said at the time in an episode of their podcast. "Jax and I are taking time apart, and I made the decision to move into another home to take some space for the sake of my mental health."
