Jax Taylor and Tom Sandoval are back at it again, arguing on Twitter.

The two "Vanderpump Rules" stars haven't been getting along during Season 8 of the Bravo reality show, which is airing currently, and that has boiled over into social media.

"When people talk [expletive] about u and don’t @ u, or the people they r talking about.. (@jeremymadix1) it should tell u a lot about who they r, and what they r saying…" the 36-year-old bar owner wrote on Wednesday. "@mrjaxtaylor stop posting fiction, get a hobby, & get off my nuts, u little whiny [expletive]."

Prior to Sandoval's response, Jax rattled off a series of since-deleted tweets that were meant to expose Tom.

"How about the fact that Jeremy, Ariana’s brother can’t work at Tom Tom because he doesn’t have the right look … are you f—king kidding me? What look do you need to have?" the SUR bartender wrote, according to Us Weekly. "#PumpRules this is about how you treat your girlfriend’s brother?"

Jax added, "Telling your [girlfriend’s] brother you belong at a tiki bar, not Tom Tom when he’s hurting for shifts? No that’s insane, Jeremy is a lot better looking and a better bartender [than] half the staff at Tom Tom. So sit [in] your pretty house while your younger brother struggles."

The 40-year-old reality star then went on to reveal that he got the information straight from the source - -Jeremy himself.

"@jeremymadix1 did you not say this to me at dinner the other day? Kind of a random thing to make up, guess will just see at the reunion," he tweeted. "Or asking him for 1 percent of his start up because he lived in your apartment and paid rent. Wow, yeah you’re a good friend all right."

Tuesday night's episode of "Vanderpump Rules" showed the duo getting along in time for Jax's wedding to Brittany Cartwright, which took place in June 2019. A lot must have happened in the eight months since, and fans will be able to catch a glimpse of the downfall of their friendship as the show airs.

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