She may be a millionaire many times over thanks to her role as Hannah Montana on the Disney Channel’s eponymous show, but it’s been Miley Cyrus‘ behavior in the past year and a half that’s truly catapulted her to superstardom.

Speaking to her close friend Kelly Osbourne for a segment on E!’s “Fashion Police,” the 20-year-old revealed that she’s frustrated by the public’s reactions to her changing image.

“People are like, ‘You know, how do you make the transformation from a kid to an adult?’ I’m like, it’s called puberty. Everyone’s done it from the beginning of time. I’m just doing it so you’re zooming in on it and you’re fascinated by it,” she said.

Cyrus also opened up about her pixie cut, which has made headlines since the second she received the drastic chop from superstar hairstylist Chris McMillan last August.

Frankly, we can’t imagine Cyrus in the long, wavy extensions of years past, but clearly, she’s undergoing an evolution!
