"She's amazing I mean she knows how to do everything, she's the most incredible actor and she's probably my biggest inspiration in life -- her and Sia, two girl empowerment, they're amazing," Ziegler said.
"You'll have to see!" she said of the project. "It's really fun and like I said, it's something completely different and something people won't expect."
Before that mystery project arrives, Ziegler is lending her voice to the animated Leap!, along with singer Carly Rae Jepsen. Ziegler is playing a not-so-nice ballerina, a character she says she's a little familiar with.
"I feel like there are so many snobby ballerinas in real life and I've had to deal with a lot of mean dancers but I guess my character's just an example of what not to be in the dance scene," she said.
But the 14-year-old has advice for dealing with the mean girls.
"Just block 'em out," she explained. "I just act like they don't matter at all and you know what? Their opinion means one thing but maybe it's just [to] them and not to anyone else you know? I can't let one person get in my way."
