Maddie Ziegler

I met Drew Barrymore, and she was so cool. She told me, 'I know I just had my baby three weeks ago, and that's why I'm emotional, but I cried when you performed.' And then she pulled out a tissue and said, 'Look, I was sobbing.'

I don't work with Sia every day; it depends what we do, whether we do performances or music videos, so the schedule is weird, but when we're off, we always try to see each other in between. We just hang out; we went to brunch one time, but for the most part I go to her house, and we eat and watch TV.
