The Jessica Simpson sex tape proved to be just a rumor, so the following may also be nothing more than a tease.

But a credible source has gone on record to say that Simpson is sick of starring in movies that bomb at the box office. Just how tired of her faltering career is this wanna-be actress?

"Jessica is in the running for a role that, if she gets it, will put her right on the map in terms of acting," the insider said, "The only hitch is that the script requires a number of quite graphic scenes including a full-frontal nude scene.

Jessica is so desperate to land the role and get the industry's respect that she's ready to go against her better judgement, and her family, by agreeing to bare all."

Good thinking, Jess. Those Tila Tequila nude photos have totally earned that celebrity the industry's respect.

Just a few months ago, of course, Crazy Joe Simpson had been confident enough in his daughter's career to turn down a role that required nudity:

"The last script that came to us was for Jessica to be a porn star," Joe said. "We were promised we would win an Oscar with that. I told them, 'I think we'll just buy a statue of a little man and keep our clothes on.'"

Now? Tony Romo may no longer be the only person seeing Jessica Simpson naked. How the mighty, not-so-talented have fallen.
