Miller also revealed that even the last half of season five, which has yet to air, is going to feature "a lot of missing Abby."
"There was an altercation at one of the competitions," Miller said, explaining why she won't be seen in a few upcoming episodes. "The producer threw me out! So I left and I didn't come back… There's about one [episode] that I just wasn't there [for]. And I thought, 'You know what? If they can do it without me, do it without me.'"
Abby opened up about the conflict that led to the incident in question, saying, "The mothers just kept riding me, riding me, riding me -- about class, about the kids taking class -- which was a complete joke to me. For the first three seasons of the show, I had to fight with production every single day about the kids getting back into their normal classes, about them disrupting my classes at my studio."
According to Miller, people often assume that, due to the show, her business must be booming. "It's the opposite!" she claims.
"Kids left because of the crew, and stepping on their bags and pushing them out of the way and all those things," Miller said. "The kids on the show need to take class, need to continue training… nothing is more important to me than them being in class."
In fact, it's the kids in her classes that Miller want to be the focus of the show, instead of their parents and the various conflicts between the adults in the series.
"I post an Instagram, I could probably have, no lie, 500 kids here within 5 hours, on one Instagram. It's the kids that watch our show," she said. "So I wish that the network would realize that, and the production company would back off the moms and the swearing and the fighting and all that, and let's concentrate on the dancing."
