Yikes, Joseline Hernandez just crossed a line and Mimi Faust is not having it!

The Love & Hip Hop: Atlanta stars have a history of not getting along, but Mimi is so done with Joseline after the self-proclaimed Puerto Rican Princess took a nasty jab at Stevie J's teenage daughter on Twitter.

Joseline tweeted an extremely nasty, vulgar response to a scene in this week's episode where Savannah — Stevie's 18-year-old daughter — told Mimi that she thinks Joseline is a "toxic" person and should not be with her dad.

"That h– mad cause I run her daddy. Now run along and find your own c–k to suck. You nappy head," the 30-year-old wrote, adding a peace sign emoji.

It was such a low blow to pick on a teenager and Jos received a ton of backlash from fans who were upset that she would say something so mean to someone who is basically a stepdaughter to her. One fan even asked Jos how she would feel if someone said that about her own daughter, six-month-old Bonnie Bella — whom she shares with Stevie — and Jos doubled down on her rude comments.

"That young lady is 18," she tweeted. "She's grown enough to [dish] it out she will [be] grown [enough] to take it!! I'm done with this conversation. Back to reality."

"In case anyone had any questions on why I was so adamant about NOT having that woman around my child…. case in point!" the 47-year-old wrote on Instagram.

Meanwhile, Stevie didn't directly call out his baby mama after she came for his little girl, but he did post a cryptic tweet about how much he loves his kids.

"I love my daughters unconditionally [and] I wish more females would experience the love of their fathers," the 45-year-old tweeted.
