Maddie and Mackenzie will talk with their dance coach Abby for the last time on screen in the upcoming finale episode, titled "Maddie and Mackenzie Say Goodbye," of the sixth season of the reality series "Dance Moms."

For the first time ever, and possibly the last time, Maddie and Mackenzie Ziegler sit down with Abby Lee Miller. They all talk about their journey on the show and say their last goodbyes to each other. They will also look back to the ups and downs of being on the show. Plus, they will be answering questions that fans have been dying to ask and the sisters will also dish out what's in store for them after their exit.

The promo trailer for "Maddie and Mackenzie Say Goodbye" shows Maddie, Mackenzie, and Abby reliving their experience together. They are seen answering questions from fans on social media. Abby may throw some attitude with the whole not giving credit to her. However, it looks like the final sit-down will end well.

Meanwhile, Miller explained to People why she has a strict teaching style. At "Dance Moms" star Jojo Siwa's 13^th birthday party, the dance coach said that it's not her intention to make her students cry.

"I am tough on the kids because someone has to be. Lordy, lordy, what if Jocelyn, JoJo's mother, said, 'Honey, you're wonderful. Honey, you're fabulous,' every minute, all day long? That is not the way to raise a child," she explained. "They have to learn a work ethic, they have to learn rehearsal etiquette and they have to learn to prioritize what they are doing in a day as far as their rehearsals and attending classes."

The previous episode, titled "The Girls Say Goodbye," saw the girls-only reunion special where the dancers say their goodbyes to the Ziegler sisters. They were also seen dancing together for the very last time.

"Dance Moms" season 6 finale episode will air on Tuesday, May 24, at 9 p.m. on Lifetime.
