"Dance Moms" season 6 star Maddie Ziegler's fame seems to have gotten the best of her.

The upcoming episode of the hit Lifetime reality TV show will be Ziegler and her younger sister Mackenzie's last competition with ALDC.

While doing the weekly pyramid, coach Abby Lee Miller asked Ziegler to open up about their upcoming departure and said that she believes no one could ever fully replace them on the team and "Dance Moms."

"I don't think anybody can fully replace us..." she said.

However, Miller didn't seem to like the fact that Ziegler has grown to be very over confident.

"So you think that we should just all throw in the towel coz you're throwing in the towel?" Miller asked Ziegler sarcastically.

Meanwhile, the clip also featured their mom Melissa Gisoni talking about her daughters' upcoming exit from the team and the show.

"It's Maddie and Mackenzie's very last dance... And that's not sitting well with Abby," Gisoni said in the teaser.

"One Last Dance" will also see one of the moms of the Mini Elite Team bringing her disabled son to watch her daughter's competition at the NYDE.

"You were talking about how excited your disabled son was to watch your daughter dance..." one of the moms asked her... and Melissa only worries about her kid," one the moms said.

Luckily, the Mini Elite Team's jazz routine "Kisses" ranked first in the mini division.

At the end of the clip, Gisoni also proved that her daughters' fame and success have gotten into her head.

"Guess what?! Your kids will be nothing!" she said.

In other news, the upcoming competitions will be a huge success for the members of the ALDC.

The Elite Team performed a hip hop routine called "Lady Bosses" that ranked first in the teen division and overall.

Ziegler's contemporary dance number "The Hostage" ranked first in the teen division and overall.
