The former model described the self-proclaimed "white Kanye" as a "sad human being," a "little boy/child" and "miserable" in his lengthy response.
James' since-deleted tweets were posted from his official Twitter account Wednesday afternoon, but he claimed he was hacked. Jax, however, insisted Bravo forced his "joke" of a co-star to remove the posts.
A rep for Bravo has not yet replied to TooFab's request for comment on the situation.
"Katie Maloney is one disgusting human. Basically making up stories about me to gain, gain, gain. Her marriage won't last, and trust me, neither will she after #pumprules," screenshots of James' Twitter page show. "And Jax?! He is just a sad man after his daddy died. Coming for me 'cause I'm the only man he don't like. Brother, make peace with your dead father, please, so you can be set free. That goes for Lala also."
Brittany rushed to her fiancé's defense by tweeting, "The disgust continues. I pray YOU will find peace some day." James replied, "Jax is the disgust that lives in most people's screens, and babe, you're engaged to it #goodluck #greatfirstwife."
Shortly after, James deleted the tweets and posted, "Damn! HACKED! I just changed my password. That should do it! Sorry, guys, you know how positive I am. Sending love to everyone today #pumprules."
Sad human being, I told you he's his own worst enemy. I feel bad for the little boy/child. He's basically telling you all what kind of person he is. https://t.co/0B5aiR4fEt
But Jax wasn't buying it for a single second. "We just found out that Bravo made him remove it," Jax tweeted. "He wasn't hacked."
James then posted (and this is the only tweet from the ordeal that remains on his page), "Hey, I'm sorry for what I said about Jax and Lala, and I apologize deeply to them and anyone I offended. I hope you guys also stop provoking me. Thank you, and I wish everyone a happy new year."
So does this mean he wasn't hacked? We can't keep up.
Hey I'm sorry for what I said about Jax and Lala and I apologize deeply to them and anyone I offended. I hope you guys also stop provoking me, thank you and I wish everyone a happy new year.
"Keep your fake-ass apology, homie. I know Bravo made you do this. We aren't idiots. Know your role in life, and keep your mouth shut," Jax continued in a tirade. "You will always be on the bottom of the totem pole in life until you figure your shit out. You're a sad, miserable human being. I feel bad for you."
Jax also replied to a fan who asked why Bravo hasn't fired James by tagging Bravo, NBC, Evolution Media and Lisa Vanderpump. "Ask them," Jax urged.
When someone else replied to the question, calling James "entertainment," Jax went off again: "Talking about my father who passed away is not entertainment."
But it didn't end there.
Jax also took aim at James' girlfriend, Raquel Leviss, who recently shared a photo of her and her boyfriend holding a puppy while at the Vanderpump Dog Foundation Gala in November. Raquel said she was "outbid by another bidder for the sweetest baby boy puppy."
You did not get out bid, we sat 10 feet from you when you attempted to bid on the puppy, you looked for money from James, he has none so he bolted and then Lisa saw it was you and told the auctioneer “no way” and gave to the next bidder. How can you lie when 300 people saw this. pic.twitter.com/tJvLFy5unN
