Maddie Ziegler Dances for Sia at We Can Survive!

Maddie Ziegler does some of her signature dance moves while performing at the 2014 We Can Survive Concert on Friday (October 24) at the Hollywood Bowl in Los Angeles.

The 12-year-old dancer joined Sia on stage. The singer never performs while facing the crowd and she was joined by Maddie to interpret the songs while she sang.

Sia performed such songs as “Chandelier,” “Diamonds,” and “Elastic Heart” during her set at the concert.

In case you didn’t know, Maddie, who appeared on the reality show Dance Moms, was the young girl featured in Sia‘s video for “Chandelier.”
