During an impromptu Facebook Live session, Kelly Clarkson surprised fans by donning a wig (similar to Sia’s hairstyle) and performing an acapella cover of her hit song, ‘Chandelier’.

Kelly announced that she was dressing up as the ‘Cheap Thrills’ singer for Halloween.

She said, “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. We’re having a big party, and anyway, I thought I’d sing in this beautiful greenhouse.”

She added, “Here you go, Sia,” she said. I hope you like it!”

 Sia recently released the deluxe version of her This Is Acting album, and included three new songs.
