Shia LaBeouf is certainly no stranger to marching to the beat of his own drum. Now, though, he's dancing to someone else's, and it's still strange!

Shia and 12-year-old "Dance Moms" star Maddie Ziegler are featured in Sia Furler's newest music video. In the video, a nearly naked and filth-covered Shia is seen cage-fighting with a dirt-covered Maddie.

The five-minute video for "Elastic Heart" begins with Shia and Maddie seemingly having a dance-off in which Shia appears startled and frightened. Later, the two seem to find a common ground and perhaps fall in love.

The strange video ends with Maddie ending up outside the cage while Shia fights desperately to get out from behind the bars.
