We first wanted to be BFFs with today's birthday girl when she played soccer star Bridget in Sisterhood of the Traveling Pants! Now as Serena on Gossip Girl, she's perfecting the term "frenemy" one catfight at a time. Happy Birthday to Blake Lively, who is celebrating her 22nd today!

Fun Facts about Blake!
-The actor who plays Bridget's dad in Sisterhood is Blake's dad in real life!
-In high school, Blake was on the cheerleading squad and in the choir!
-Disneyland was California-born Blake's favorite place growing up -- she would visit sometimes twice a week!!

Leave your happy birthday wishes for Blake below!
