Jessica Simpson is ready to go fully nude for a new movie that she believes will launch her into the Hollywood A-list.

The singer-turned-actress reckons that she will be taken more seriously in the film industry if she goes naked for her ‘art’ - even if it goes against her family's wishes.

Hasn’t Heather Graham proved that it tends to work the other way?

A source said: "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 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."

Meanwhile, Jess reportedly went “nuts” at Eva Longoria for talking to her ex John Mayer.

An insider tells Page Six: "When Jessica heard that Eva was being friendly and polite to John, she called her a back-stabber and was furious."

However a rep for Jess said: "There's no truth to Jessica being upset with Eva Longoria. They are great friends."
