I know what video mom2 is referring to. It's a video that a participant took with her phone at a Master Class(?) Abby was teaching somewhere in Pittsburgh. I don't know how to share a link, but here's how I found it. First search for Abby Lee Miller. About three or four items from the top you'll see an article that starts out, "You know, I always thought Dance Moms was totally scripted, but..." Near the top of the article is a link to the video. (The word "Video" is a live link.) The article is from just a day or two ago.
Most of the video is Abby answering questions after the class. Supposedly recording devices weren't allowed, so the person recording stayed behind Abby...so you see mostly Abby's back. Gianna, Maddie, Kendall, and Nia were there too. Maddie was introduced last and got the biggest round of applause, but not bigger than when Abby first came in and was introduced. (Go figure.)
There's clearly tension between Lifetime and Abby on several issues. Apparently, Christy and Chloe were about to be expelled from the dance company, when Lifetime chose them to be on the show. Abby still wants to get rid of them, but she can't. She says her problem with Chloe is that her mom is dragging her around the country for meet and greets, instead of spending more time dancing, and Chloe's dancing has suffered as a result.
Cathy wanted out of the show at one point, but Lifetime didn't want to lose her. So they said she could pick her own team, etc. Abby's not happy because she says she didn't get to pick her own team.
Abby also says Brooke and Paige are only at her studio when the show is filming. They don't dance there any other time.
I think the video was filmed in February (Abby mentions Valentine's Day) so I think it was shortly after the moms had stayed in the parking lot on "strike." it sounds like that was completely because they wanted something more (money?) from Lifetime. Apparently they were out there for several days. Abby says something about, "They had to do what they had to do," but she had to have dancers, and that's why they brought in replacements.
It was eye-opening for sure. The show supposedly has a huge audience, in many countries. Nobody involved at the start thought it would last very long. Abby says Lifetime ordered six more shows before the first six shows had aired, which apparently is very unusual.
