Let's say you're a talked-about young billionaire who runs a controversial though wildly popular company. Then let's say a not-so-flattering movie comes out about you, about the possibly shady way in which you got control of your company from early collaborators, and most importantly about your basic lack of human emotion. How do you combat the bad press? You could try revealing photos of your girlfriend.
According to the nearly unreadable Today 24 News (apologies for this site; reports right now are limited), the pair met when Zuckerberg was attending Harvard University, where she was studying medicine. This makes their relationship at least seven years old.
So what does this tell us about Zuckerberg? Not much. The portrayal of the tycoon in Fincher's film is harsh, to be sure, suggesting he's a cold, manipulative cipher with more talent for betrayal than business or technology. The fact that he has a girlfriend doesn't necessarily contradict this. After all, Charles Manson had a girlfriend.
