There's no warm welcome for Abby Lee Miller in her final Dance Moms appearance.

A new sneak peek of Miller's last days on the Lifetime reality show was released this week, and it doesn't take long for things to explode when the 50-year-old dance instructor returns to say her final goodbyes.

"Why are you back? You don't want to work with the kids, they don't want to work with you," an upset mom yells at Miller in the clip.

"It was like, five years of my life," a tearful Miller replies.

In March, the reality TV star quit Dance Moms, telling ET that she was "finished working under these conditions."

Filling in for Miller is Cheryl Burke, who gets greeted with open arms. "They didn't trust Abby to be with their girls," Burke says. "I'm not going to yell at them, I'm not going to judge them for their appearances. I do not like her way of teaching sometimes."

A Dance Moms source told ET that once Burke joined the team, "the production breathed a sigh of relief."

Last month, Miller was sentenced to a year and a day in federal prison for bankruptcy fraud. ET caught up with her in Philadelphia, Pennsylvania, immediately after she pleaded guilty and received her sentencing.

"I feel relieved," she told reporters, including ET, outside the courthouse. "I feel peaceful."

When asked how she will adjust to life in prison, she said she knew there would be a few physical limitations and dietary limitations -- especially pressing given Miller's recent gastric sleeve surgery -- but she'd "be OK."

"It's a realm of the world I know nothing about. I just know what I know and I do the best I can," Miller added.

Season seven of Dance Moms will premiere August 1 on Lifetime.
