Born on August 25, 1987 into a showbiz family in Tarzana, California, Blake Lively made her film debut at age 10 as the Tooth Fairy in the indie film, Sandman (1998), directed by her father, Ernie Lively, a well-known character actor with over 100 screen credits. Blake's mother is a talent agent, while her older siblings Lori, Jason, Eric, and Robyn are all established actors themselves. However, Blake decided to concentrate on school first, becoming class president and a cheerleader before returning to acting. Just before beginning her senior year of high school, Blake landed a starring role opposite Alexis Bledel, Amber Tamblyn, and America Ferrera in the major motion picture The Sisterhood of the Traveling Pants, with her real-life dad playing her on-screen father. She has also appeared in many other films including Simon Says and Accepted.
