Siblings Mackenzie and Maddie Ziegler will take their final bows in the upcoming episode of "Dance Moms."

In "Dance Moms" season 6 episode 18 titled "One Last Dance," the members of the Abby Lee Dance Company (ALDC) will practice routines that they will perform at the New York Dance Experience to be held in Riverside, California. However, it seems like for Abby Lee Miller, it is not fine to just let the sisters leave the show without any drama.

In the promotional video for the episode, dance mom Jill Vertes says, "It's Maddie and Mackenzie's very last dance, and that's not sitting well with Abby."

The official synopsis for the episode reveals that saying goodbye will not be easy for mother Melissa Gisoni either. Based on the synopsis, Melissa will be asked by the other dance moms to "stand up to Abby" following the coach's decision to pick a new team member. However, Melissa will divert her anger to them instead of Abby, taking out her umbrage on the wrong people.

Meanwhile, Abby will say her final words to Maddie. Preview for the episode suggests that Maddie will announce that she does not think than anyone can completely replace her and her sister Mackenzie.

After "Dance Moms" season 6 comes to a close, Maddie Ziegler will no longer have to complete with the elite junior team. However, fans of the Ziegler sisters will not have to miss them so much as they will still appear in the reunion specials of the network.

"Dance Moms" season 6 episode 18 airs on May 3, 9:00 P.M. on Lifetime.
