Ziegler is back in her skin-colored body suit and blonde bob, though this time she's engaged in a dance-off with a shirtless, grubby LaBeouf.
While many have praise the clip for its art and emotion, some viewers took to social networks to declare their outrage over the intimacy portrayed by the actors. One tweeted, "The new Sia video is disgusting," and another wrote that the video would be "magic if her dancing partner wasn't 30 years old, looked like a child predator and was a good dancer." Elle Magazine tweeted that the video was "creepy".
Sia responded with a string of tweets. "I anticipated some 'pedophelia!!!' Cries for this video. All I can say is Maddie and Shia are two of the only actors I felt could play"
She described the in-video performance as "These two warring 'sia' self states."
And continued, "I apologize to those who feel triggered by #ElasticHeart My intention was to create some emotional content, not to upset anybody."
"Chandlier" director Daniel Askill and choreographer Ryan Heffington again lent their talents to "Elastic Heart", which has generated more than 2.6 million hits on YouTube in less than 24 hours.
It's Sia's latest single from her sixth album 1000 Forms of Fear, which debuted at the summit of the Billboard 200 albums chart last July. The song has origins dating back to late 2012, when it was included on the soundtrack to The Hunger Games: Catching Fire and featured the Weeknd & Diplo.
