"Dance Moms" star Abby Lee Miller gave a tearful farewell to her dancers and their moms in a dramatic new teaser video released Wednesday for the Lifetime program's final season. After seven seasons, the show is set to take its last bow on Lifetime's summer lineup on Monday, August 1, and Miller said she regrets "everything."

Miller launched the flagship location of Abby Lee Dance Company (ALDC) in Pittsburgh 35 years ago. She shared her thoughts on her business and the dancers she's created in the season eight promotional video.

"I created livelihoods for so many children," Miller said. "It was all going to end someday."

The dancers and mothers, who have stood by the choreographer through the roughest patches, decided to bring in new leadership to replace Miller. Laurieann Gibson — who has worked with Beyoncé — made a cameo as a guest choreographer in the promo trailer, driving tensions higher within the ALDC group.

"There's a new f—g b—h here up in this town," Gibson said. "My guns are fully loaded."

However, the arrival of "Dancing with the Stars" pro Cheryl Burke proved to calm the nerves of the award-winning team because her leadership style doesn't utilize harsh tactics. But Miller wasn't pleased.

"I don’t need one of them," Miller said. "I don’t need any of them."

Miller then added, "I regret it. I regret it. Oh, I regret everything."

The drama continued in the trailer as former ALDC member Chloe Lukasiak revealed her return to "Dance Moms." However, Lukasiak will not dance alongside the ALDC girls. Instead, she will be dance against her former teammates.

The Lukasiak's mom, Christi Lukasiak, said in the clip "the amount of pressure [for Chloe], it's about a zillion percent."

Since Lukasiak chose to dance on her mother's old competition team, the ALDC moms voiced their lack of supportive of the Lukasiak's decision and called her out for playing the "victim" card.

After filming for season seven wrapped in March, the woman behind ALDC revealed her departure from "Dance Moms" in an Instagram post. Miller felt that it was a "critical time" for her to address this decision.

"I will no longer take part in 'Dance Moms,'" she wrote. "For the past six years/seven seasons I have asked, begged, and even demanded creative credit for all the ideas, award winning routines, and costuming to no avail."

Miller then added that she had no problem working with the ALDC children, but she was tired of being "manipulated" by the show's producers.

"I don’t have a problem working with any kid. I love children and have dedicated my life to making other people’s children successful," she said. "I just have a problem with being manipulated, disrespected, and used day in and day in and day out by men who never took a dance lesson in their lives and treat women like dirt."

ALDC and "Dance Moms" is a major part of Miller's life. However, she will be forced to say goodbye to it for good as she prepares to serve her prison sentence for a year and a day. Miller received jail time for bankruptcy fraud and for illegally bringing $120,000 in Australian currency into the United States, according to a May report from ABC.

The reality television star pleaded guilty to all charges.

Miller has been known for her controversial coaching tactics and her award-winning dance routines. Through the success of ALDC in Pittsburgh and "Dance Moms," Miller launched an ALDC studio in Los Angeles and other reality programs such as "Abby's Ultimate Dance Competition."

One of the most successful dancers to come from the ALDC studio is "Dance Moms" star Maddie Ziegler. Ziegler is known for her appearances in Australian pop singer Sia's music videos. Since leaving the reality show in 2016, Ziegler has gone on to be a judge on "So You Think You Can Dance" and star in upcoming movie "The Book of Henry."
