CALGARY -- Is Hilary Duff the good girl the world wants to think she is?

While the Lohans and Hiltons of the world are off getting their party on, the 19-year-old actress/singer/Stuff By Duff fashion designer has always maintained her apple-pie image, even while dating Good Charlotte member Joel Madden, eight years her senior, who is now expecting a child with Nicole Richie.

Nonetheless, one can't help but speculate whether Duff's squeaky-clean reputation is simply maintained by a shadowy group of puppet-string pulling publicists.

This may all be changing, however, as she appeared in a photo shoot for Maxim last month, and is set to co-star with John Cusack in the self-described "controversial" film War Inc., in which she plays a pop star who "uses her body to get what she wants".

"It's so interesting to me because for such a long time people have said, 'Oh, she's the good girl, she's this, she's that'. But really, I'm just kind of normal," Duff said in a phone interview before her show in Winnipeg last weekend.

"I act my age, but I also have respect for myself. There's a certain way that I want people to see me, and it's not far off from how I really am. Still, I don't need people to know everything about me."

While her Maxim photo-spread is by no means R-rated, it's still more suggestive than any pre-teen friendly projects Duff has been involved with in the recent past.

Is this her attempt to change the way she's viewed?

"I don't think that I'm going out of my way to shed any sort of image," she says. "People have watched me grow up, so maybe it's different for them, and I'm just doing things now that maybe aren't crazy, but are definitely a bit older. I'm older, and I'm not going to stay the same way forever.

"If you look at the Maxim shoot, it's very classy, and not the normal thing people do for them. They approached me about a year ago to do it originally, and I said no, but when they approached me again this year, it just seemed like the right time."

Duff also mentions she's covering Pat Benatar's Love Is A Battlefield on this tour.

"I like so much stuff, I'm all over the place," she says. "But I still love Morrisey, and The Cure, and I love Rancid. It depends on my mood."

At her not-quite-sold-out show at the 'Dome last night, the median member of the audience was a 10-year-old girl with blond hair and braces. As the lights dimmed and the glowsticks in the audience spun, a backing band of rag-tag rockers and a few breakdancers took to the stage, before the now-brunette star herself stepped out.

Duff was dressed in silver short shorts and a sleeveless top, accented with studded bracelets and black fingerless gloves. As the faux-Euro dance beats of her new sound blared behind, her banter and stage presence were small to non-existent, but the crowd ate up every second of it.

When she broke into her hit song Come Clean, even the dads in the room could be seen dancing, and the screams were near-deafening.

She may be growing up and trying new things, but Hilary Duff's fanbase is the same it's always been.
