Top 50 Under 25

Blake's the first of many ladies from Gossip Girl on this list, because Gossip Girl is like a starlet natural preserve or something. In fact, originally, we pitched this article as just "50 Hottest Women on Gossip Girl," but our editor felt it was too narrowly focused, and we had to go and pad it out with young starlets who were not on Gossip Girl.

To be fair, Ms. Lively originally hit the scene as part of the cast of The Sisterhood of the Traveling Pants, in which she was one of four girls who shared a magical pair of pants that made special things happen to them. In Blake's character's case, the magical pants cause her to lose her virginity to some dreamy coach at soccer camp (which, really, is a great excuse to tell your angry parents when they find out: "I didn't MEAN to, Daddy, the magical pants WANTED to come off!")
