Birthday: April 17
Hometown: Bedford, NY
Where You’ve Seen Her: We first noticed the gorgeous Rooney Mara in 2010’s The Social Network as Erica Albright, the girl who dumped Mark Zuckerberg. In addition to early guest appearances on ER and Law & Order: SVU, she earned an Oscar nomination for the gritty role of Lisbeth Salander in 2011’s The Girl with the Dragon Tattoo, and also starred in this year’s Side Effects. Catch her next in Ain’t Them Bodies Saints, out August 16. Ain't that a weird name for a movie?
