In an interview with ET Online, the 12-year-old dished on what it's like to be Sia's muse, backup dancer and close friend.
"She's literally the sweetest person ever," Maddie said. "I feel like I'm just so comfortable with her every time I'm with her and I never feel like, 'Oh my God, I'm hanging out with a celebrity.'"
Well, that works out perfectly, especially since Maddie has previously stated that she doesn't really consider herself to be a celebrity. Clearly, the pair have a more down-to-earth relationship that goes far beyond matching blonde wigs, red carpets, performances and video shoots. After revealing that they pretty became BFFs on the spot the first day they met, Maddie admitted that she's even seen the "Chandelier" singer throw down in the kitchen.
"She cooks for me," Maddie revealed. "She's such an amazing person."
Um, can you blame Maddie for totally gushing over Sia? If someone cooked for us, we'd probably be singing their praises too. But that's not all — Sia's also been kind enough to give her some pretty awesome career advice.
"She definitely told me to stay humble." Maddie continued, "If I'm getting pushed to do something I don't enjoy, to definitely let everyone know just so I'm not doing something I'm passionate about."
Maddie's already on her way to the top, but we totally love that she has a fellow female mentor and friend who's there to make sure that the ride is as smooth as possible.
