So Shia LaBeouf thinks he can dance.

The actor appears in Sia's very artistic video for "Elastic Heart," where he's engaged in a bizarre (and beautiful) dance battle with "Dance Moms" alum Maddie Ziegler.

This is Maddie's second music video for the singer, who also had the 12-year-old star in the clip for her smash hit "Chandelier" last year.

Sporting nothing but a pair of nude boxer briefs, LaBeouf puts his insanely ripped physique and contemporary moves while covered in dirt.

Maddie dances circles around the 28-year-old inside a giant steel cage for the 5:07 video. 

Our favorite part: Those faces Shia makes around the 3:40 mark. Priceless!

What do you think of the clip? Some have criticized both this and the "Chandelier" video for sexualizing Ziegler at such a young age ... but it comes across as more artistic and less exploitative to us.

Commenters on the video's YouTube page also suggest the video could be about Sia's own relationship with her father.

There's a lot to think about here, which is usually the case with interpretive dance, so we definitely want to hear your thoughts -- sound off below!
