It looks as though Dance Mom's Abby Lee Miller has two favorites when it comes to her dancers. Not only does she supposedly give 11-year-old breakout star Maddie Ziegler quite the advantage on the show, but her younger sister Mackenzie, too.

According to Miller, Mackenzie is staring in a new Christmas video, which she is currently filming in Los Angeles. The controversial dance instructor posted several videos of Mackenzie in hair and make-up and filming scenes on her Instagram account on Friday.

Maddie Ziegler Says Australian Singer Sia Was Starstruck By The Dancer  

Back in July, Mackezenie's mother Melissa Gisoni defended Miller, saying that television audiences are yet to see another, softer side of the reality television star.

In a new interview with In Touch Weekly, Gisoni says that the drama gets so intense on the show, that she and her daughters have a hard time swallowing all the "hate" that comes their way from the other dancers and their moms.

"It bugs me. I know that it's really hard to the other girls when Abby pays more attention to me," Ziegler said in the interview. "It's true, they don't get as much attention. But, I don't think it's right for the other moms to talk bad about me or behind my back. It hurts my feelings. And watching them yell at my mom, it makes me said."

Gisoni added, "I always tell the other moms that if they would just let some of the things Abby does roll off their shoulders, things would be easier. There's another side to Abby, too. She loves to fool around with the kids and play with them. She shops for them constantly! But they don't show that."
