Singer Sia set the Grammy Awards stage on fire Sunday with the help of surprise guest Kristen Wiig.

The former “Saturday Night Live” star channeled Sia as she danced along to the singer’s hit song, “Chandelier.”

As the performance began Sia stood at the back of the stage facing the wall as Wiig and “Dance Moms” veteran Maddie Ziegler donned the singer’s signature massive white wig.

Even before taking the stage, Sia and Ziegler had heads turning on the red carpet when they showed up in matching wigs.

The 12-year-old Ziegler has been Sia’s constant collaborator, starring in her music video for”Elastic Heart” alongside actor Shia LaBeouf, as well as in the video for the mega-hit single “Chandelier.”

The special performance had viewers in stitches.
