"Welcome! Hey, what's up? I'm Sia this Halloween. What?!" Clarkson hilariously announced to her viewers while sporting Sia's famous face-covering white locks. "She's one of my favorites, so I thought I'd wear a wig and be Sia. I'm gonna cover a Sia song right here real quick, and I'm gonna talk to you."
"I've had a full day in New York, and now I'm back in Tennessee, and this is our succulent wall that we're having for our masquerade ball that we're having tomorrow night," she said, pointing to the wall behind her. "We're having a big party, and anyway, I thought I'd sing in this beautiful greenhouse."
"Anyway, this is called 'Chandelier,' so here we go. Here you go, Sia. I hope you like it," she said, giving a shout-out to the singer before starting her performance.
