Miss Miley Just "Can't Be Tamed"
For the past four years, Miley Cyrus has been a multi-million dollar baby as face of Disney's hit TV show, "Hannah Montana."
But now, Cyrus is 17, and singing a new tune a little more adult than the ones that made her famous.
The sexy new persona Cyrus is trying on for size might be her way of growing up and out of her squeaky clean image, but many in her legions of fans aren't impressed, reports CBS News Correspondent Michelle Miller.
She talked to some teens who once emulated the actress and pop-star, to try to find out why they've had a change of heart.
"She used to be my role model, but now, as she's getting older, she's just changing my thoughts,' said Kristina Anzilotti.
Cyrus may be losing fans faster than she is gaining them, Miller points out.
Her newest album, "Can't be Tamed," earned 72 percent less than her album from two years ago, "Breakout," and 33 percent less than her most recent one, "Time of Our Lives."
Why the dramatic decrease? It may be that Cyrus is growing up a little faster than her audience, or that the little girls who've watched her for years just don't buy the act, Miller says.
"I don't think she needs to grow up," says "Hannah Montana" fan Alyssa Sansone. "I think she grew up enough."
While many may not like her new image, many industry observers thinks the timing is perfect for Cyrus to put on her big-girl shoes.
"She's got a ton of momentum right now," said Jennifer Armstrong, senior writer at Entertainment Weekly. "Everybody knows who she is. It's time to make the transition."
Cyrus' metamorphosis started two years ago, when she posed almost nude for a Vanity Fair spread, and escalated with her risqué performance at the 2009 Teen Choice Awards, which included a pole, and some booty shaking.
"I do understand that she's getting older and she needs to move on. I do get that," said Jennifer Anzilotti, mother of a Hannah Montana fan. "(But) I don't think she needs to hang from poles."
As the last season of "Hannah Montana" comes to a close, it'll be a long way from the wonderful world of Disney for Cyrus and her followers, Miller says. While several divas before her have made their way from "Mouseketeer" to chart-topping, album-selling ladies by embracing overt sexuality, many observers worry that Cyrus is aiming for an R-rated image while trying to keep her PG-audience.
