Since the age of two, Maddie Ziegler has had a passion for performance. Raised in Pittsburgh, Pennsylvania, Maddie's mother Melissa enrolled her and her younger sister Mackenzie in dance classes at a local studio. A few years later the trio starred in the hit Lifetime reality series 'Dance Moms'. The result of the show's immense popularity led Ziegler to segue into becoming an viral dance sensation, starring in singer-songwriter Sia's music videos for 'Chandelier', 'Elastic Heart', and 'Big Girls Cry', which have collectively amassed more than 1.5 billion views. Maddie has performed these dark contemporary routines on shows such as Jimmy Kimmel Live! (2003), Saturday Night Live (1975), Ellen: The Ellen DeGeneres Show (2003), and The 57th Annual Grammy Awards (2015). Ziegler has since begun acting on scripted television shows, such as Pretty Little Liars (2010) and Austin & Ally (2011). She makes her major motion picture debut in The Book of Henry (2017), opposite Naomi Watts, Jaeden Lieberher, and Jacob Tremblay.
