Ever since Blake Lively appeared in her first major movie, 2005's "The Sisterhood of the Traveling Pants," we've seen her grow from a "Gossip Girl" into a woman right before our very eyes, trading the glamorous Upper East Side on TV for grittier, acclaimed roles on the big screen. Not to mention, she's just about the hottest actress in Hollywood today and the nicest California girl around.
Happy birthday, Blake! You've definitely got a lot to celebrate today (and not just your hot BF, Ryan Reynolds).
And we can celebrate by flipping through Lively's Hot People Looking Hot gallery. It's our lucky day, too.
