Jessica Simpson turned down the chance to win her first Oscar--because the film role she was favored for was too risqué.

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."
