Demi Lovato has a special relationship with her fans, and she showed it in a recent performance on her South American tour. Lovato answered questions during her sound check in Rio de Janeiro, Brazil on Friday (April 19) -- starting with the "craziest thing" she's ever done.

When a Lovatic asked what the craziest thing Lovato's ever done for an idol, Lovato scratched her head and broke into a smile. "The craziest thing I've ever done for an idol ... I tried to sneak backstage at a concert for the Academy Is...," she giggled. "In like, sixth, seventh grade when I was obsessed with them I tried sneaking backstage." Now that Lovato's a superstar, we doubt she'd need to do that anymore!

When a fan asked how Lovato felt about coming back to Brazil, she was more than enthusiastic. "You guys are one of the most extreme cities I've ever been to," she said. "And I mean that in the best way possible. Seriously, y'all are insane and I love it!"

Fans also asked Demi about her favorite One Direction song and member. "My favorite song is 'What Makes You Beautiful,'" Demz said, tugging at her braid and giggling, "and my favorite is Niall!" No surprise there, PopCrushers!

Lovato also touched on more serious topics, like how she stays strong. "I pray everyday, I meditate," she said. "And I'm very thankful for you guys, and I really honestly think that if it weren't for you guys, I wouldn't be standing here today."

So sweet! Tune in below to find out about Lovato's favorite super hero and her favorite show that she's ever performed, as well as some of her Sao Paulo performances.
