Musician Sia is famous for her unconventional performance style. She doesn't appear in her music videoes. For the past two, Elastic Heart and Chandelier, she let former Dance Moms dancer, 12-year-old Maddie Ziegler perform on her behalf. Maddie wears a platinum bob wig, just like Sia's.
This week, the 39-year-old Aussie did make an appearance while Maddie performed Elastic Heart on The Ellen DeGeneres Show. Sia was one of the heads that popped out of a white box. Sia kept her face covered with her wig which was equipped with extra long bangs. Sia told Ellen, and her guest Jimmy Fallon, that she will perform at the Grammy Awards show on February 8 on CBS, home of Ellen.
