If you thought the first half of “Dance Moms” Season 5 was dramatic, just wait until you see the reunion special. The synopsis for the forthcoming episode, titled “Seeing Stars,” teases Abby Lee Miller will battle it out with several dance moms.

Ever since Holly Frazier teamed up with Danity Kane singer Aubrey O’Day for her daughter Nia Frazier’s music video debut, she has been on the outs with Abby. According to the synopsis for episode 19, the dance mom and the ALDC coach will “go head-to-head” during the reunion. And that’s not all that is set to go down.

Cathy Nesbitt-Stein of Candy Apple's Dance Center and Jeanette Cota of Broadway Dance Academy will also reportedly cameo. “Abby’s nemeses, Cathy and Jeanette, stir things up,” Lifetime’s summary for the episode reveals.

For viewers who are not fans of the mom drama, you’re in luck. Lifetime has revealed that the ALDC girls will also take center stage during the episode. Maddie Ziegler, 12, who is fresh off her third music video with Australian singer Sia, will reportedly discuss her newfound fame. The network teases that the Grammy performer will also be revealing “upcoming events” she has in the lineup. Could she be announcing a release date for her first single?

Maddie isn’t the only dancer appearing on the reunion special. Maddie and her teammates will be performing some of this season’s most popular dances. In a promo for the episode, posted below, it appears they will be performing their award-winning “American Horror Story: Freak Show” and “Orange Is the New Black” inspired group routines.

The entire cast will then reportedly reflect on “all that they’ve learned, shared and lost during their time at the ALDC,” according to the synopsis. To conclude the episode, Abby, who is about to open her West Coast ALDC LA branch, will dish on her “plans for world domination."

Episode 19 of “Dance Moms” Season 5, "Seeing Stars," airs Tuesday at 9 p.m. EDT on Lifetime. The second half of “Dance Moms” Season 5 is expected to return later this year and kick off with the ALDC’s trip to Australia.
