See Kelly Clarkson Cover 'Chandelier' in Sia Wig for Halloween

"I don't know how she does this, 'cause, ya know, you can't see," Clarkson says of Sia's signature, eye-shrouding blonde bangs

Kelly Clarkson donned a replica of Sia's signature, eye-shrouding wig and belted a pre-Halloween cover of "Chandelier" during a Facebook live session. Standing in front of a flowered wall in her Nashville home, the singer performed an a capella version of the 2014 hit, nailing every ghostly high note and melismatic swoop.

"I don't know how she does this 'cause, ya know, you can't see,” Clarkson joked afterward of Sia's hair. "But it's also kind of awesome, because you're in your own little world when you're performing … I love that song. Everybody loves that song."

After the performance, Clarkson promoted her second annual all-star Miracle on Broadway Christmas benefit show, set for December 16th at downtown Nashville's Bridgestone Arena. The event, which benefits four local charities, also features Reba, Ronnie Dunn, Kelsea Ballerini, RaeLynn, the Steeldrivers and Chip Esten.

Clarkson is currently prepping her eighth album, due out in 2017. The LP, which taps R&B and soul influences, will follow 2015's Piece By Piece, which drew heavily on contemporary electro-pop and EDM sounds.
