Hilary Duff has revealed that she is a virgin and intends to remain so until she marries boyfriend Joel Madden.

The 18-year-old actress-turned-singer insists she won't have sex before walking down the aisle with her Good Charlotte fella, although she did admit the couple have shared a bed together before.

Hilary told Yahoo: "It's harder having a boyfriend who's older because people just assume.

"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."

Hmmm, didn't Britney Spears say the same thing once upon a time?
