Though she’s only 24, Blake Lively has already put together a resume that most actors can only dream of having.
The blond bombshell, who celebrates her birthday today (August 25), first hit Hollywood’s radar as one fourth of the Sisterhood of the Traveling Pants in 2005. Two years later, she officially reached super-stardom when she landed the role of Serena Van der Woodsen on the hit CW series Gossip Girl.
