Lifetime's "Dance Moms" is a widely watched television docu-series that highlights the struggles of being a talented dancer's mom, how hard young dancers have to work in order to make it in the industry and the demanding nature of infamous coach Abby Lee Miller.

Episode four will see Abby really making demands to her students as the competition at the World-Class Talent Experience in Woodbridge in Virginia draws closer. According to International Business Times, Jojo, who is 11 years old will replace Abby Lee Dance Company (ALDC) member Nia Frazier, who is 13 years old, in a bid to lower the average age group. With Nia the group will have to perform in the teen division, but with Jojo they can compete in the junior category. Holly Frazier, Nia's mother, makes her disappointment apparent. The promotional clip, released by Lifetime, shows a distraught Holly asking Jojo if Nia's feelings are more important or winning the competition.

It looks like there is enough drama as the competition heats up and is aired in the upcoming episode. Jill Vertes, who is the mother of Kendall, agrees with Abby's decision to remove Nia as she wants to do whatever is necessary to win. In the promotional clip you can see Jill saying, "A child never has to dance older than they are."

Speculations are also rife that the "Dance Moms" may take matters in their own hands and use other avenues to progress their child's career. Maddie Ziegler, a student of ALDC and just 12 years old, bagged two Hollywood gigs, Sia's "Chandelier" and "Elastic Heart", making other moms tempted to go behind Abby's back to secure Hollywood gigs for their own children.

The group will perform a lyrical jazz routine known as "Frozen Together", in which they win second place overall. Maddie bags second place overall for her number "She's History" while Kendall and Jojo got third place but failed to bag a spot overall in the competition.

"Bye Bye Pittsburg" will air Tuesday, Jan. 27, 9 p.m. EST on Lifetime.
