Sia De-Wigged Last Night: Here's Proof

Sometimes girl just has to put her hair up.

Sia's most recognizable feature is definitely not her face -- she usually keeps it hidden under a massive umbrella-like wig or, rather, she just turns toward the wall when she's in public. So when you actually do see Sia baring a smile, well, you don't automatically know it's her.

The oft-costumed singer shed her masked persona for Elton John's 2015 Oscars viewing party on Sunday night. While she kept hidden under lampshade hair while walking alongside husband Erik Anders Lang on the Vanity Fair party red carpet, she later exposed a new side-bun 'do and a face like sunshine. She was probably just relieved she didn't have to sing in a corner that night!

Sure, I know what you're thinking: So what? Sia has a face. Um, yeah dude, she has an incredible face, and we only see it twice a year. Of course I'm excited about it.

Look at her hanging with Heidi Klum! The happiest!

And while Miley doesn't look super enthused in this pic, Sia is all smiles while meeting up with Ryan Seacrest at the Vanity Fair party, where she was also wig-less. Right now she's probably laughing off some lame small-talk wig joke, like "Oh, Sia, we didn't know you had eyes!"

I suppose when you're going to a viewing party, you must actually want to be able to view. And, plus, sometimes you just need to put your hair up!
