Maddie Ziegler also revealed in her memoir that connecting with Australian singer-songwriter Sia in 2014 and appearing in the music video for "Chandelier" was a life-altering moment. "Before I met [Sia], I would say yes to a lot of things I didn't want to do ... Sia always tells me you have to have time off, step back and appreciate the moment" (via Teen Vogue).

A lot of people were amazed that Maddie penned her memoir at such a young age. After all, she was only 15 years old when her book was released. She told ET that her motivation was just to make sure people really know who she is. "I feel like a lot of people know me but there's a lot of things that they haven't learned yet. So, I'm here to teach them tips and tricks and a little bit more about my life."

She also said that she understands why people might think they know more about her than they do. "People think they know everything about me from Dance Moms or my Sia [music] videos, and I guess I understand how they might feel that way. I mean, I was completely hooked on Gossip Girl, and I felt like I knew all of the characters on that show personally. We were family" (via ET).
