After years of portraying the teenage TV character Lizzie McGuire, Hilary Duff is all grown up in the new video for her next single, "Come Clean."

While the 16-year-old Duff still looks basically the same as she does in the clip for her current single, "So Yesterday," it's her emotional portrayal that has matured in line with the song's reflective theme. Unlike her bratty first single off Metamorphosis, which told its listeners the only requirement for implementing change is a desire to do so, "Come Clean" is about looking at a situation carefully to fully understand what's at the heart of the matter.

"I'm shedding every color/ Trying to find a pigment of truth/ Beneath my skin," Duff sings in one verse, before launching into the chorus of "Let the rain fall down/I'm coming clean."

Showing Duff's contemplative emotional side and shattering the happy-go-lucky persona most of her fans are familiar with wasn't easy for video director Dave Meyers (Missy Elliott, Pink), who shot the "Come Clean" video on Sunday in Los Angeles.

"I'm trying to do something where you're taking her very seriously ... very dramatic and very feminine, and sort of almost sensual," he said before the shoot took place. "I don't think we’ve ever seen that from her. She's been a bit of a pop icon, so I'm just trying to give her a bit more credibility on an artist front."

Meyers took the rain reference Duff uses in her song and ran with it. The video is set in her house over the course of a rainy day. It opens in her bedroom with Duff singing in the sweats and tanktop she slept in. By the end of the day, the camera has moved to the bathroom, kitchen and living room, where Duff is eventually joined by her bandmates. As she moves from room to room, the camera periodically focuses on the rainfall outside, which gets stormier as the chorus comes around each time.

The inside scenes are intercut with close-up shots of a mysterious man in a car. In the end, he pulls into Duff's driveway where she comes out to greet him. The final shot is of a rain-soaked Duff about to speak to the person she's spent all day thinking about.

"We never do know if the guy in the end is a boyfriend or friend or what the drama is," Meyers said. "It's just all very photogenic and sophisticated and not too colorful."

While "So Yesterday" continues to garner top-40 radio play, both the "Come Clean" video and single are expected to surface in mid-January.

Duff has four more headlining shows slated before she tackles at least nine radio-sponsored package shows before the holidays (see [article id="1480499"]"Hilary Duff Steals Little Hearts at Phoenix Tour Kickoff"[/article]).
