HOLLYWOOD -Being a teenage sensation can be exhausting. Just ask Miley Cyrus.
It means performing your current hit, "The Climb," on American Idol and at the Academy of Country Music Awards, accepting a miniature orange blimp for favorite female singer at the Nickelodeon Kids' Choice Awards, gracing the cover of the latest Glamour magazine, attending Hollywood premieres and starring in your own - according to the teeny-bopper barometer - wildly successful show.
It's a lifestyle Cyrus has mastered. At a recent meet-and-greet with the media at the Four Seasons Hotel, she's wide awake after having gotten little sleep the night before. And she's gushing about her boyfriend as she checks her BlackBerry. She's doing what she does best. She's just being Miley.
"It's so much fun," said the 16-year-old. "I have these amazing opportunities, and I'm doing what I love."
The frenzied schedule, which Cyrus chronicles on her Twitter account, is apt to get more chaotic as Hannah Montana: The Movie, a big-screen adaptation of the popular Disney series, hits theaters Friday.
If the success of her 3-D concert movie, Hannah Montana and Miley Cyrus: Best of Both Worlds - which took in $31.1 million on its opening weekend in February - is any indication, fans are likely to swarm theaters to catch their favorite wig-wearing star.
Or will they?
The movie's soundtrack debuted at No. 2 on the Billboard 200, selling 139,000 units - a fraction of the opening numbers of Cyrus' previous releases. And the recent less-than-rocking box-office opening of Jonas Brothers: The 3D Concert Experience further calls into question whether the hysteria surrounding Disney's most celebrated teenage stars is calming. But Cyrus isn't too worried.
"I think, you know, we're at a bad time in our economy," said the singer-actress, who takes time to compose her thoughts before answering questions. "There's always doubt in my mind that this could all slip away overnight, but I try not to dwell on it. I definitely don't want to go out and say this is going to be the biggest movie of the year because I'll just be setting myself up for a downfall."
But, for now, the media whirlwind continues. In addition to the film, Cyrus recently released her autobiography, Miles to Go, which begins with her sixth-grade year and chronicles her road to Disney stardom. It offers a toned-down look at the media darling who is frequently tabloid fodder.
