I just learned that Rooney Mara, the star of "The Girl With the Dragon Tattoo," is also the actress who played Erica Albright (Zuckerberg's girlfriend) in "The Social Network."

I can't believe it! How did that sweet, girl-next-door character become the world's most famous Femme Fatale?

Check out the Youtube clip, below, of Mara breaking up with the Zuckerberg character and compare it to the magazine cover.

Hey, just for kicks, here are pictures of the REAL Erica Albright. She's no Rooney Mara, but if I were Mark Zuckerberg I would have been broken hearted.
