Check out Blake Lively's sexiest looks!
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.

Of course, as people quickly learned, Blake’s good looks and talent were way too big for the small screen. Soon, she was cast in a number of high-profile movies, including Ben Affleck’s The Town, in 2010, and this summer’s big-budget blockbuster, Green Lantern.

And that was just the beginning. Blake, who has already positioned herself as one of the up-and-coming fashion icons of her generation, is currently working on Oliver Stone’s latest movie, Savages, opposite John Travolta, Uma Thurman, Salma Hayek, Taylor Kitsch and more.

Oh, and she’s rumored to be dating another movie star — hottie Leonardo DiCaprio — which should make her big 24 the happiest birthday ever.
