This is the music video that had everyone talking on Wednesday.

Starring a half-naked Shia LaBeouf and 12-year-old "Dance Moms" alum Maddie Ziegler, Sia's clip for "Elastic Heart" is definitely emotionally charged -- but left some people screaming "INAPPROPRIATE!"

In the video, the two have a dance battle inside a giant cage. A dirt-covered, boxer-brief wearing LaBeouf puts his insanely ripped physique and contemporary moves on display, as Ziegler dances circles around him.

The commenters in our own original post yesterday were split down the middle about the artistic video.

"Shia LaBeouf has some sort of mental illness. Mattie Zeigler's [sic] parents also have some sort of mental illness, sexualizing their 12 year old this way," wrote one. 

"This isn't a video about sex, it is a video about humans and struggle," posted another. "Didn't see a sexual connection at all."

"Just feel the ick slithering from the video. She's 12 and this is just inappropriate," another added.

Let's just say there was A LOT of back and forth on the subject.

Overnight, Sia addressed some of the criticism -- which she says she was already expecting.
