American Idol winner Jordin Sparks has pledged to wait to have sex until she's married. The pretty teenager, who became the youngest Idol winner in May (07), reveals she promised her parents she'd keep her virginity until her wedding night when she was just 13. She explains, "My parents gave me a purity ring and talked to me about waiting until I'm married to have sex. It wasn't forced; it just made perfect sense. "It's going to be awesome to say to my husband that I waited my whole life for him."
