Just when the founder of Facebook is looking to clean up his image, a new expose reveals the uber-geek as an unrepentant sex maniac!  

Mark Zuckerberg, 26, will be laid bare in a new film The Social Network from West Wing creator Aaron Sorkin.

The  UK Times reports six years ago Zuckerberg created what was to become the internet phenomenon Facebook in a "tidal wave" of grief after being dumped by his girlfriend.

The biopic begins in 2004 when Zuckerberg, then 19, was dumped by his girlfriend Erica in a Harvard bar.

In the script, Erica charges Zuckerberg will "go through life thinking that girls don’t like you because you’re a tech geek. I want you to know, from the bottom of my heart, that that won’t be true.

"It’ll be because you’re an asshole."

Shaken, Zuckerberg retreats to his  dorm in a drunken fury and writes the computer code turning Harvard’s web page of student photographs  into a website where he and his male buddies rank their female classmates as barnyard animals.

Thirty minutes after "Thefacebook" goes live, it crashes Harvard’s computer network.

The film then shows Zuckerberg, played by Jesse Eisenberg, dropping out and moving to Silicon Valley where he builds Facebook with Sean Parker, of  music piracy site Napster, played by Justin Timberlake.

According to the film, after Zuckerberg quit Harvard his personal life spun out of control, as his new business partner Parker helped him indulge his sexual fantasies with a steady stream of willing "groupies" and that while Zuckerberg partied Parker ran the biz until a $4 billion buyout.

Sorkin’s screenplay suggests Zuckerberg was driven to succeed by sexual insecurity feeding a newly engorged libido, flushed with fame and money.
