Stassi Schroeder and Lisa Vanderpump are still feuding.

Last night, during the third installment of the Vanderpump Rules season four reunion, Schroeder and Vanderpump came to blows once again after Schroeder's infamous solo sex tape.

"Andy Cohen wasted no time cutting to the chase and reminding everyone that the issues with Stassi’s sex tape went way back. Like, all the way back to the finale for the previous season," Us Weekly revealed on Monday.

As fans of Vanderpump Rules will remember, Schroeder accused Scheana Marie Shay of watching her sex tape during the season three reunion, and while she admitted to doing so, she denied having anything to do with the potential sale of the flick, which Vanderpump put a stop to.

"[Vanderpump] put up the $900 of hush money that kept the tape away from the public, [but] Lisa never felt like Stassi was too appreciative of the money she dropped on the younger woman’s dignity, and that battle played out during this reunion," the magazine explained.

“I was saving your ass!” Vanderpump informed her former employee.

And when Schroeder attempted to explain her side of things, Vanderpump quickly cut her off.

“No, no,” she interrupted. “Don’t be ridiculous!”

Schroeder and Vanderpump's issues with one another stem back to season two, when Schroeder suddenly left Los Angeles without so much as a goodbye to Vanderpump, who was her boss at the time. Since then, Schroeder has made a number of questionable statements about Vanderpump, and refuses to acknowledge anything she's done for her.

In late 2014, Schroeder appeared on a Podcast, where she dissed Vanderpump as an "old woman" and accused her of being in her business.

"I still love SUR. I love going into SUR. I still have so many friends there that just aren't on the show. I grew up there a little bit. [Lisa], like, doesn't like me. I don't understand what her problem is. [She's] like an old woman, why does [she] care what I'm doing?" Schroeder said.

In response, Vanderpump was reportedly upset, and a source told Perez Hilton she felt as if Schroeder had "no loyalty what so ever."

"She's provided all these wonderful opportunities for her and doesn't get a thank you. The entire cast dreads filming with her and on many occasions have refused to film with her," the source said at the time.
