So much for Joseline Hernandez and Mimi Faust’s newfound friendship. The pair has been somewhat getting along on Season 5 of VH1’s “Love & Hip Hop: Atlanta,” but everything seems to fall apart in a sneak peek of Monday’s episode 16.

In the video, Dawn, Joseline, Mimi, Rasheeda, Ariane and Karlie Redd are all sitting around at Ariane’s listening party but no one is talking. Dawn senses the awkward vibe and asks why everyone is so “uptight.” It appears that Joseline is the reason for the group’s sour mood. When Mimi starts to answer Dawn, Joseline cuts her off calling Mimi a “fake a-- b----.”

The two exchange some words and Joseline hurls an insult at Mimi, asking if she liked it when she took her “husband” — referring to Stevie J — and then gave him back to her when she had enough of him. The clip ends with an angry Joseline grabbing her drink and throwing it in Mimi’s face.

Earlier in the season, Mimi and Joseline kind of made up. The self-proclaimed Puerto Rican Princess even cried to Mimi about Stevie supposedly getting another woman pregnant. When Mimi found out Joseline lied to her, she once again lost all respect for her ex’s “wife.”

In an Instagram post a few weeks ago, Mimi slammed Joseline, calling her a “nut bag” after she alleged that Stevie J had molested their daughter Eva. Posting a screen shot of a news outlet debunking Joseline’s claims, Mimi wrote: “At least some journalists are responsible enough to research the real story #WhenTwoNutBagsCollab.” Mimi also called her co-star “Satan’s spawn” in an interview this month. 

“Lover & Hip Hop: Atlanta” airs Mondays at 8 p.m. EDT on VH1.
