Life is sweet – and getting even sweeter – for the pop world's favorite girl-next-door. Sure, Hilary Duff starred in a monstrously huge TV show but that's, like, so yesterday 'cause Hilary Duff's exercising her right to change her mind and act her age. No more trying to fit a circle into a square. With her first real pop-rock album, Metamorphosis, and the #1 single "So Yesterday," Hilary Duff is finally free to be who she wants to be.

MTV also hosted a prestigious premiere for the "So Yesterday" music video on its July 21 presentations of Making The Video and TRL All-Star Backyard BBQ and featured Hilary Duff in MTV Diary. Duff recently was a presenter at both the MTV Video Music Awards and the Nickelodeon Kids Choice Awards, where she accepted the trophy for "Favorite TV Show" on behalf of Lizzie McGuire. And although there’s not one molecule of space left for another top award her shelf, "So Yesterday" has become the #1 most-streamed video on AOL.

What kind of music can fans expect from Hilary Duff on Metamorphosis? A chameleon-like variety of changing moods, from the romantic ballad "Where Did I Go Right?" to the ultimate break up song, "So Yesterday." From the tough-talkin' "Party Up" to the hard rockin' "Little Voice."

t's difficult to comprehend all that Hilary Duff has accomplished in the past few years. Prior to Metamorphosis, Hilary Duff had already sold 2.2 million albums, spent six weeks in the Billboard Top 10 and earned two platinum album awards. She has starred in one #1 television series, two hit movies, and has already made two more major films (20th Century Fox’s Cheaper By The Dozen with Steve Martin, and Warner Bros.' A Cinderella Story) to be released later this year. Plus, not one but two television specials will honor the big day she turns "Sweet Sixteen."

Not bad for someone who really just wants her driver's license.
