Abby Lee Miller's replacement on Dance Moms has quite a bit of experience on the ballroom floor and with reality TV.
ET has exclusively learned that Dancing With the Stars pro Cheryl Burke will be joining the Lifetime show for the remainder of the season after Miller -- who has been the no-nonsense dance instructor on the series for six years -- announced on Monday that she was quitting. As for Burke, 32, she has served as a professional dancer on 19 seasons of DWTS, but is not currently competing on the ABC show.
According to a source, Dance Moms will resume filming on Wednesday, and has been picked up for four more episodes this season. "It's a go with or without Abby," the source told ET on Monday. "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]."
Meanwhile, a second source told ET that "[Abby] bolted from [filming] three or four episodes recently." ET was also informed that the show had to bring on celebrity choreographer Laurieann Gibson to teach the girls in place of Miller.
Sources also shared that Gibson filmed for three weeks and was supposed to come back to shoot a fourth episode when Miller returned with a list of demands, including nobody mentioning "jail" and Gibson not being allowed on set.
Another one of our sources said that Miller was "spiraling and making decisions that most people would think are not smart."
Miller, however, said in an Instagram post that she was quitting the show because she "ASKED, BEGGED, AND EVEN DEMANDED CREATIVE CREDIT FOR ALL THE IDEAS, AWARD-WINNING ROUTINES, THEMES, AND COSTUMING."
Meanwhile, the 50-year-old dance instructor 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 said before jokingly adding, "Maybe I need a few months' vacation."
