Duff's no strip vow

Hilary Duff has vowed never to strip off for the sake her acting career.The pretty actress-turned-singer says she wouldn't resort to nudity just to boost her profile or land a movie role.She told Britain's Sunday Telegraph Seven magazine: "If I do a movie I want to be myself. I don't want to take my top off or anything. In the States, it seems it's the trend to turn 18 or 19 and then take your shirt off and do something crazy, and I don't know what comes after that.'
