We know something is coming at Sunday's VMAs...
...and now we have a better idea of exactly what that might be!
Wow, we could watch Sia perform Chandelier all day long…even if we don't get to see her magical face!
In the vid, Sia sings with her back to the audience as a much older version of the songstress lip-syncs the lyrics on a treadmill.
Yep, that sounds like our girl!
Check out Sia's senior citizen doppelgänger below…AFTER THE JUMP!
Between the musical goodness and magnificent visuals, we're just blown away!
