"Dance Moms" stars Maddie and Mackenzie Ziegler are two of the closest siblings on the hit Lifetime reality TV show.
Just recently, the 13-year-old "Chandelier" dancer showed support for her younger sister by promoting her new Christmas song "Sleigh Ride."
In return, Mackenzie was also present when her older sister performed "Alive" with Sia on "The Ellen Show" this week.
The 11-year-old even shared a photo of herself and her sister sitting on Ellen DeGeneres' and the guest's chairs.
However, as close as the two are with each other, the "Elastic Heart" dancer recently revealed that Mackenzie also gets jealous of her sometimes.
In an interview with Yahoo News, Ziegler said that she and Mackenzie are always in competition with each other.
"The Book of Henry" star added that Mackenzie sometimes feel upset that more people want to interview her.
"But that's just her being my sister. If she was my friend, she wouldn't care," she said.
Meanwhile, Mackenzie also talked about her older sister in one of her YouTube videos.
The talented performer said that she and Ziegler are so competitive with each other, but they also love spending as much time together.
Mackenzie added that Ziegler tends to be bossy at times, but that's just her natural way of showing that she's protective of her, according to Design N Trend.
Even though the Ziegler siblings are both professional dancers, they actually specialize in different routines.
The older Ziegler is known for her lyrical solos, and Mackenzie is more into acrobatic and group dances.
The Zieglers will return to "Dance Moms" season 6 on Jan. 5, 2016 on Lifetime.
