As multimedia momentum goes, no one need teach 19-year-old Hilary Duff a thing. For the past decade, she has built a career that began on TV, peaking in 2001 with her title role in Disney's 65-episode "Lizzie McGuire," making her a name brand among tweens. Two years later, she recorded a full-length studio album, "Metamorphosis," which catapulted to No. 1 on The Billboard 200, and the single "Come Clean" hit The Billboard Hot 100's top 40. The project sold 3.7 million copies -- and a MTV star was born.

With "Dignity," due this week via Hollywood, Duff is coming out with the majesty of a high-class debutante. Duff co-wrote all songs on the album with A-lister Kara DioGuardi, including the uptempo single "With Love."

"People don't know a lot about my life, but these songs are self-explanatory. It was crazy to be in the midst of a loving relationship, then not knowing why you're still there, then not being in it. I cover these emotions and the feeling of being in the dark," she says.

Even so, the melodic template of the album is refreshingly dance/pop. "It's so different from my other albums, which were pop/rock," Duff continues. "I didn't necessarily plan the album to sound like this, but it was so easy to write to."
