The 50-year-old reality TV dance instructor took to Instagram on Monday to reveal that she is leaving the Lifetime show after six years.
"The majority of children that follow me may be fast asleep, however now is the critical time to make the following statement: I WILL NO LONGER TAKE PART IN DANCE MOMS," Miller announced in a lengthy Instagram post. "FOR THE PAST SIX YEARS/ SEVEN SEASONS I HAVE ASKED, BEGGED, AND EVEN DEMANDED CREATIVE CREDIT FOR ALL THE IDEAS, AWARD WINNING ROUTINES, THEMES, AND COSTUMING - TO NO AVAIL!"
"I don't have a problem working with any kid, I love children and have dedicated my life to making other people's children successful!" she continued. "I JUST HAVE A PROBLEM WITH BEING MANIPULATED, DISRESPECTED, AND USED - DAY IN AND DAY OUT BY MEN WHO NEVER TOOK A DANCE LESSON IN THEIR LIVES AND TREAT WOMEN LIKE DIRT!"
ET reached out to Lifetime, but the network said it had no comment at this time.
However, a source close to the production tells ET, "The show will continue shooting and the producers hope Abby returns to lead her team."
For now, Dance Moms will go on with or without Miller.
Multiple sources connected to the show tell ET that the cast and crew learned Monday that they have been picked up for four more episodes for the current season.
"It's a go with or without Abby. It's been up in the air because the network said it's either all of the cast or they weren't doing any [more episodes,]" one source says.
A second source shares, "She [Miller] bolted from [filming] three or four episodes recently."
ET has also learned that production had to bring on celebrity choreographer Laurieann Gibson to teach the girls in place of Miller. "She's [Miller] spiraling and making decisions that most people would think are not smart," another source says.
The sources add that it's unclear right now if Gibson will choreograph the girls for the four episodes that were ordered today, explaining, "She filmed with the girls for three weeks. She filmed three episodes and then she was supposed to come back the fourth week and then Abby came back."
ET was told that when Abby returned from her three-week hiatus from filming, she had a list of demands for everyone on set.
"We weren't allowed to say jail, we weren't allowed to say anything to the likes of jail and Laurieann Gibson is not allowed around," the second source claims.
Production for the show resumes on Wednesday.
The trouble between Miller and Dance Moms has been brewing for some time, as the dance coach expressed her frustrations with the production to ET at the OK! Magazine party last month.
"I literally dropped a bomb on them, because I have been doing all the costume design," she said. "And my accountant said, 'This is ridiculous! You're losing money, wasting time and not getting paid.'"
"I get a budget from them, but I don't get a salary to do the work. So, I said, 'Forget it," Miller added. "I handed the producer, the main a**hole, I handed the check back today for the costume budget, and I go, 'Oh, by the way, I'm not doing the costumes anymore.' And he just went like this, like the blood drained out of his face. 'Oh my god, what are we gonna do?' I don't know, maybe go over to Dancing With the Stars and hire a few seamstresses. Buy some fabric downtown and make them yourself!"
Meanwhile, Miller is awaiting sentencing after pleading guilty to bankruptcy fraud last June.
With the potential of facing up to 10 years in prison, Miller told ET she was staying positive ahead of her sentencing hearing, which was originally scheduled for Feb. 24, but was subsequently delayed. No future date has been given.
"I'm good. I try to stay positive and happy ... I know I made some mistakes along the way, but I've pleaded to all those," she conceded, joking, "Maybe I need a few months' vacation."
