Maddie and Mackenzie Ziegler have finally said their last goodbyes to "Dance Moms." And though coach Abby Lee Miller was said to have been disappointed over the famous sisters' exit, she recently slammed the rumors and said she's actually happy for them.

According to Design & Trend, Miller said during the last episode of "Dance Moms" season six that she doesn't feel bad about the Ziegler sisters' decision. Instead, she's happy that they have decided to take a step forward in their careers.

In the episode titled "Maddie and Mackenzie Say Goodbye," Miller, who was the long-time teacher of the sisters, explained that she's looking forward to what the future has in store for them. Despite their departure from the show that gave them their big break, Miller hopes that she can continue to work with her former students.

Both Maddie and Mackenzie were also given time to thank Miller for her influence on their careers and personal lives. Mackenzie said, "Thank you for giving us all these opportunities."

Meanwhile, viewers are now voting for their pick to be nominated as the "Choice Dancer" at the Teen Choice Awards 2016. While Maddie had been urging her fans to vote for her, Chloe Lukasiak, who is also a "Dance Moms" alumni and is considered by many as Maddie's biggest rival, has also been doing the same.

According to The Bitbag, Lukasiak is also rumored to return to the show for season seven now that Maddie is out. On the other hand, the outlet says Lukasiak's return may actually pose a threat to the other students on the show who haven't been given the chance to shine.

Despite the speculations about Lukasiak's return for the upcoming season, it appears that she might not have time for the series since she is working on other projects. Just recently, the young dancer announced on Instagram that she will be having a new series titled "Dance Classes with Chloe."

Lifetime has yet to announce when "Dance Moms" season seven will start airing.
