Dance Moms
During her time on Dance Moms, Maddie was known to be Abby's favorite. This often caused tension between the moms and Abby, with them arguing that the other girls deserved just as much attention.

Maddie and her family chose to leave the show mid-Season 6 to continue other projects.

Sia
Maddie gained worldwide attention in 2014 after appearing in the music video for Sia's "Chandelier". She has since gone on to become a notable part of Sia's artistic image- appearing in many other music videos for the singer as well as touring with her.
