Just to have a history check on how Blake Lively started..

"In 1998, when she was only 10 years old, Blake made her acting debut in the film Sandman. The film was directed by her father and also starred her sister, Lori, and brother, Eric. In the musical family movie, Blake played the Tooth Fairy. She stayed away from all other acting jobs after her debut in Sandman to be a regular elementary- and middle-school student," as quoted from www.askmen.com.
