Australian singer Sia doesn’t like to show her face, but if that means we get to see Dance Moms’ Maddie Ziegler dance, we’re cool with it. Maddie already has appeared in Sia’s music videos for “Chandelier” and “Elastic Heart,” and even performed with the singer on major shows like the Grammy Awards and The Ellen DeGeneres Show. The little lady bring it again for Sia’s video “Big Girls Cry,” showing she doesn’t need a big stage to put on a great dance performance. All eyes are on her as she creates a manic scene to the emotional song. She might only be 12 years old, but there aren’t many dancers or performers who can pull this off.
