Kelly Clarkson is channeling another pop star for her Halloween costume: Sia.

The American Idol alumna donned the Australian singer’s trademark wig for a Facebook Live chat Friday evening and offered a soulful rendition of “Chandelier,” Sia’s massively popular 2014 single.

“Here ya go, Sia. I hope you like it,” said Clarkson before performing the a cappella cover. She later added, “I love that song. Everybody loves that song.”

As for the wig? “I don’t how she does this, ‘cause, you know, you can’t see,” Clarkson said. “But it’s kind of awesome, because you’re in your own little world when you’re performing.”
