Leave it to Sia to raise some eyebrows. The singer, who notoriously objects to fame and avoids showing her face on camera, enlisted the help of funny lady Kristen Wiig and Dance Moms' Maddie Ziegler for her Grammy performance last night.

During her performance during music's biggest night, Sia faced the back wall of a messy room and sang her hit tune "Chandelier," as Ziegler and Wiig danced it out in the space.

The two wore matching blonde bob wigs and jumpsuits and eventually stripped down to nude bodysuits.

Sia, who was nominated for four Grammys, including Record of the Year and Song of the Year, did her best to keep her face hidden last night. The Australian kept her face from the camera during her "Chandelier" performance and when she was on the red carpet -- she donned an oversized wig which covered most of her face.

We don't care what Sia does or how she looks -- as long as she keeps making that amazing music!
