The "Fire Meet Gasoline" video is the Sia and Heidi Klum collaboration we never knew we needed.
Legendary music producer and founder of electronic music Giorgio Moroder will release his first solo album in over 30 years. And now we have a first taste — featuring Sia!
She may be adamant about not showing her face on camera, but Sia knows how to deliver a truly captivating performance even from behind her trademark blond wig.
Sia once again teamed up with the insanely talented 12-year-old Maddie Ziegler for her "Big Girls Cry" music video.
For those truly curious about the woman behind the metaphorical (and, sometimes, physical) mask, we've gathered more than 30 photos of Sia's face.

This is one Grammys collaboration we definitely did NOT see coming: Sia and Kristen Wiig together onstage for 'Chandelier'!
Sia has just unveiled her contribution to the 'Fifty Shades of Grey' soundtrack with an emotional new ballad called 'Salted Wound.'
Sia made her 'Saturday Night Live' debut last night (Jan. 17) where she performed her hits 'Chandelier' and 'Elastic Heart.'
Sia is not surprised that her controversial video for 'Elastic Heart' has elicited "pedophilia cries" -- but she is sorry.
