WATCH: Sia Is Ready to Reveal the Secret Thing Hidden Behind Her Hair

What’s behind door number one?

Sia is known for hiding behind her extraordinary hair (lest we remind you of the 2015 Grammys?). This move is deliberate. She wants to maintain her privacy despite mega-fame so that she can tinkle anonymously on the side of the road without a gross paparazzo getting “the shot”. Leave it to daytime’s Mother Teresa Ellen DeGeneres to coerce Sia into revealing what’s hiding behind her overgrown bangs.

Could it be a head? A third nipple? Amelia Earhart?? Or does she just have a zit?

Watch Sia’s wind-up for her big reveal in the video above, and watch the full shebang happen live today (Dec. 1, 2015) on her episode of The Ellen DeGeneres Show.
