Sia Crashes '80s Mall in Throwback 'Move Your Body' Lyric Video

If you were alive in '80s America, but never had your glamour shots taken, did you truly live?

In Sia's new lyric video for This Is Acting's "Move Your Body," the "Alive" singer/songwriter takes us back to an American mall in 1987, highlighting a denim-clad family cheekily posing with gargantuan cell phones. But after the young daughter spots Sia's now iconic black-and-white bobbed wig, she makes a run for it and begins dancing through the entire photo studio, charming other portrait subjects as she goes.
