Hilary Duff may be dating Joel Madden, but the punk rocker hasn't seen much more of this singer/actress than any fan. How is that possible? Because Duff claims she wants to remain a virgin until her wedding night.

Hey, it worked for Jessica Simpson. Until that awful, public, humiliating divorce.

Duff, 18, is intent on remaining true to her V-card, however. She's upset when fans automatically assume she and Good Charlotte star Madden are have swapped much more than spit.

"It's harder having a boyfriend who's older because people just assume," she said. "But (virginity) is definitely something I like about myself. It doesn't mean I haven't thought about sex, because everyone I know has had it and you want to fit in."

Poor Madden, though. He'll have to wait a bit before he can fit into his girlfriend.
