Maddie Ziegler of Dance Moms fame has another starring role in Sia’s latest video, Elastic Heart. Maddie’s co-star in the video is Shia LaBeouf. Now there is and interesting choice. I guess this means Shia is ready to be famous again. Elastic Heart is from the same autobiographical body of work in which Sia explores difficulties in her past. In Chandelier, the first video that Maddie did with Sia, the topic of addiction was the theme. In Elastic Heart, the artist explores her difficult relationship with her father who some say also had difficulty with addiction and mental health issues.
