Love her or hate her, there's no denying the polarizing force that is Lena Dunham, creator and star of Girls. As if a hit show that seems to have all the world talking (and was just renewed for a third season) weren't enough, the 26-year-old two-time Golden Globe winner recently inked a $3.5 million deal (yes, you read that right) with Random House to publish Not That Kind of Girl: A Young Woman Tells You What She's Learned, a book of essays.
