Jessica Simpson turned down the chance to win her first Oscar - because the film role she was favoured for was too risque. The busty pop star/actress' manager father Joe has revealed his daughter was offered the role of a porn star in an upcoming film, and told the movie could be her big chance to take home a Best Actress Academy Award. Joe Simpson, a former Baptist minister, says, "The last script that came to us was for Jessica to be a porn star. We were promised we would win an Oscar with that. "I was like, `We'll just buy a little man (Oscar) and keep our clothes on."
