Blake Lively got her start in Hollywood with The Sisterhood of the Traveling Pants films - the first of which premiered in 2005 - and never looked back. Shortly after playing Bridget in the coming-of-age movie, Lively landed the role of Serena van der Woodsen on The CW's Gossip Girl. The teen drama, which premiered in 2007, shot the actress to superstardom and her star has only risen in the decades since.
