Sia Stepped Up Her Wig Game by, Like, 20 Notches at the Grammys

Sia hit the red carpet for the Grammy Awards in a giant white wig on Sunday. The singer was joined by dancer Maddie Ziegler, who has appeared in Sia's "Chandelier" and "Elastic Heart" videos as well as multiple performances; the pair wore matching black pants and tailored jackets, and Maddie even sported a smaller version of Sia's shocking mane. This is hardly the craziest look we've seen on the singer, who has become famous for thinking up new ways to hide her face. Sia is nominated for four awards tonight and will also be taking the stage for a performance during the ceremony.
