Just a few weeks after Facebook CEO Mark Zuckerberg and Priscilla Chan's wedding, Zuckerberg is reportedly being sued by FB Investors claiming that he sold more than $1 billion worth of the company's shares just before prices started to fall. Shareholders also claimed that Zuckerberg knew the stock was overvalued and dumped his own shares to avoid continued losses. The lawsuit was filed on June 3, in the U.S. District Court in Manhattan, includes Goldman Sachs, JP Morgan and Morgan Stanley.
