Lifetime's hit show, "Dance Moms" teases that things are heating up between the competitive mothers concerning the favoritism toward Maddie Ziegler.

The 12-year old dancer has enjoyed much success in the past year, mainly with her appearances with pop singer Sia in her music videos "Chandelier" and "Elastic Heart."

The mothers are now voicing their concern in the fact that none of their daughters will receive the same opportunities in their recent trip to Los Angeles. Along with this, their dance instructor, Abby is said to put priority on Ziegler's career.

The network has provided a short synopsis on the upcoming episode:

"LA is only one week away and JoJo and Jess return to fight for a spot on the ALDC and are determined not to lose again. As the team prepares for their big Hollywood adventure, Holly and Jill grow concerned that Abby's focus will only be on her favorites and Nia and Kendall will be forgotten. After hearing about Maddie's next big Los Angeles opportunity, Holly and Jill vow to take matters into their own hands."

Abby's favoritism for the girls' with the most potential been a reoccurring premise for the show.

It also isn't only Maddie receiving all the attention anymore, as her little sister Mackenzie, only 10 years old, has recently been breaking out into the scene.

"Ryan Seacrest wants to interview Maddie [and] Mackenzie. They're in another magazine, which is great!" The girls' mother, Melissa commented.

Melissa has been seen addressing the jealousy of the other mom's and expresses her gratitude to entertainment icons like Sia for opening so much doors for her girls.

"My biggest thing is I have meetings set up for Maddie on her two days off," Melissa says in a preview. "She's reading a script right now for a new show."

"Dance Moms" episode 4 will air on Tuesday, Jan. 27th on Lifetime.
