Alicia Keys is urging parents of teenage girls to take school uniforms seriously - because they're not a turn-on for horny boys. The R+B star has launched a campaign aimed at prompting young girls to save themselves for sex - and she thinks uniforms have a large part to play in keeping lusty youths away from temptation. She explains, "Uniforms definitely do help. I mean, naturally a girl or a woman is going to dress how they want to dress... It (a uniform) gives you less options to do that kind of thing." And Keys hopes her young fans follow her example and cover-up to keep the boys guessing. She adds, "You are more mysterious and more intriguing when you cover it up."
