Lucy Hale, who drives a Prius to work at "Pretty Little Liars," confirms that we’ll soon find out the identity of the mysterious manipulator known as "A." "The core of the show has been finding out who A is and I'm curious to see how the viewers will react, and how the writers will go on from there," says Hale, who believes that the ABC Family series' dense plot, high drama and investment in the characters will continue to keep people tuning in. "I love the fact that each girl is so different and the writers have made each character so relatable. You really feel for them. You feel for Aria and Ezra when they can’t be together," she says of her storyline. "I feel like that's what makes the show successful."

On Jan. 22, Hale stars in "A Cinderella Story: Once Upon a Song" — an ABC Family original movie in which she plays an aspiring singer whose dreams are continually thwarted by her cruel stepmother (Missi Pyle) and stepsister (Megan Park), who also get in the way of her crush on the new boy in school.
