Cameron and Tyler Winklevoss, the twins who gained fame through their portrayal in the blockbuster movie "The Social Network," are reportedly preparing to sue Facebook founder Mark Zuckerberg once again.

The Social Network portrays Mark Zuckerberg as a deceiving person who duped his colleague (Cameron and Tyler Winklevoss) in Harvard University to take full control of social networking platform Facebook.

In real life, Winklevoss brothers sued Facebook founder in 2004, claiming he stole the idea and code for the social networking site. The twins won the suit and get away with $65 million from Mark Zuckerberg.

But, now reports are emerging that the twins are planning another lawsuit against Mark Zuckerberg, accusing him of security fraud. They are also claiming that he lied to them about company’s value.

The leaked court document states, “Their fraud claim is based on omission: They fault Facebook for not volunteering a more recent--and, they claim, lower--valuation of different Facebook stock.”

But as usual, Facebook is denying reports, saying there is no new litigation between the site and the twins.
