Miley Cyrus is only 17-years-old, but she’s acting more like a rebellious 22-year-old! “She doesn’t want to be seen as a young teen anymore,” a source tells BettyConfidential. “She wants to break out and become a sex symbol, just like her new pal, Gossip Girl’s Blake Lively. She idolizes her. In her mind, she’s done being Hannah Montana. She wants to be a sexy pop star.”

“Ever since Miley and Blake met in 2008 at the Teen Choice Awards in Hollywood, Miley has been so taken with Blake that she decided she wanted to edge up her act a little. Blake is a star of a hit show, she’s beautiful, is a fashion risk-taker and her long sexy legs and long blond locks have made her one of the sexiest women in television. Miley already has the long legs and the hit TV show, now she’s styling her hair like Blake! They actually look like they could be related.”

On Miley’s recent tour, you couldn’t see any signs of Disney’s goofy high-school student. She was dressed in leather mini skirts, belting out tunes with special effects and shocking visuals, astounding her 9-year-old fans and their moms in the audience. “Miley is hoping to change her fan base to those in their late teens,” the insider says. She’s already turning heads on the red carpet with plunging necklines and sexy dresses.

“She’s driving Disney mad,” adds the source. During the summer, it seemed like every time Miley went out in public she would do something shocking, like pole dance at the Teen Choice awards, the racy Twitter pics and now she’s gotten a tattoo, with the words, Just Breathe, under her breast. “This is not what Disney had in mind for her.”
