"Dance Moms" veterans Chloe Lukasiak, Nia Sioux, Kendall Vertes, Kalani Hilliker and Camryn Bridges have formed a dance group called The Irreplaceables, and they will be debuting their more mature dance routines.

Sneak peeks of their dance number called "The Last Dance" have been circulating online.

Of course, anything "mature" is bound to get mixed reactions from coaches. The promo video from Lifetime shows former coach Abby Lee Miller and one other mom from the Abby Lee Dance Company (ALDC) sounding disgruntled by The Irreplaceables' routines.

"Those are not the dancers that I raised!" Abby is seen saying. "I'm very disappointed. It's the epitome of trash."

Lukasiak's mother Christi recently tweeted that she is excited to watch her daughter perform with her original teammates.

Although she did not tweet anything herself, Christi did retweet fans' posts calling out Miller for previously allowing "mature" acts herself, such as season 1's "Electricity" number and the "topless" season 2 performance.

Hilliker's mother Kira also took to Twitter to express her excitement for the girls' performance.

"Who is ready to see these teenagers take on a dance that challenges, grows them as dancers and prepares them for the professional world! ME!" her tweet read.

Regardless of what the moms think, the dance competition judges get the final say.

As what will be shown in the upcoming episode 24 of the show, The Irreplaceables reportedly scored only second place in the teen division of the Fierce National Dance Competition in March.

Meanwhile, ALDC managed to get not just one, but two big wins. Miller's team bagged first place with the reboot of the routine "Where Have All the Children Gone?" and second place overall.

In episode 25, the jazz dance routine "The Protest" will lead to the group getting third place for that performance, while the group placed fifth overall.

"Dance Moms" season 7 airs Tuesdays at 9 p.m. EDT on Lifetime.
