It looks like there are going to be some major changes for the Dance Moms cast next season, and Abby Lee Miller might be one of them. There's a new report that says the controversial dance instructor is threatening to leave the series. What's more, she's barely even seen in the last half of season five, too.

According to Entertainment Tonight on Friday, Miller made it clear that there is a lot of friction between her and execs at the Lifetime network right now.

She said, "Lifetime is a little in arrears on their payment plan with me personally, and so I think that will have to be taken care of first before we talk about season six. The last half of season five, which has yet to air, is going to feature "a lot of missing Abby."

Miller also explained that the show's producers are probably going to try and film the series without her, even though she is one of the biggest celebrities in the reality television world right now.

She explained, "There was an altercation at one of the competitions. 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.'"

And if that weren't enough, the actual dance moms at the studios aren't making things easier, too.

Miller added, "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."
