It doesn’t appear things are going swimmingly for the cast of “Dance Moms.” Amid rumors of a casting switchup on Season 6B of the Lifetime reality series, coach Abby Lee Miller has revealed some serious animosity on set.

Abby took to Instagram Sunday to say there is palpable “hatred” at her West Coast studio, ALDC LA (Abby Lee Dance Company Los Angeles). “Today should have been a time to mourn, to reflect, to be grateful for all that we have,” she wrote. Her post was accompanied by a shot of the American flag and came hours after the deadly shooting at the Pulse nightclub in Orlando. “It wasn’t. I felt the hatred in the air on set today!” she continued. “Now I’m hash tagging #dancemoms #season6 because that’s where I was.”

Abby made her complaint the same day the show filmed an episode for Season 6B. According to one spoiler site, the cast appeared at New York Dance Experience in Upland, California, on June 12. Once again, elite junior member JoJo Siwa, who is rumored to have quit the show along with her mother Jessalynn, did not compete. The elite junior team, dancing to a hip-hop number, reportedly did not place in the overall teen division. But Abby’s mini team pulled through, placing in the overalls for their contemporary number “Casting the First Stone.”

This isn’t the first time Abby has used social media to complain about rivalries on set. In December, ahead of the premiere of Season 6, Abby revealed that she was upset with one unnamed producer for trying to assign one of her dancers a teen pregnancy routine.

“Week after week, for 26 weeks at a time — I am forced to take their cockamamie ideas and somehow morph them into thematic dance routines suitable for the stage and our very young audience, yet remain competitive enough for a real dance competition,” Abby wrote in an ALDC newsletter. “When a grown man tells me he wants one of my kids to portray a pregnant teen and wear a baby bump — I have to put my foot down. If that means not moving my foot and not working and getting fined in the process, well that’s a risk I am willing to take to protect my girls.”

Two months later, she revealed yet another rivalry with production. Abby shared via Instagram that at episode 15’s competition one crew member didn’t let a pal of hers visit her backstage. “One of the producers went off on our friend and stylist to the stars,” Abby wrote. She concluded the incident was enough to make her “turn to ice and freeze the room.”

Lifetime has not announced a premiere date for the back half of “Dance Moms” Season 6.
