Alison DiLaurentisplayed by Sasha Pieterse
It's been a year since Alison disappeared, but she's been present in her friends' minds ever since. She was their Queen Bee, and the most popular girl in school. She knew everybody's secrets, but since she's been gone her friends are beginning to realize how little they really knew about her. (They do seem to know more about her mysterious disappearance than they're letting on, though.) Now they're getting strange messages from "A" – messages that include info only Alison would know. They also catch glimpses of someone who looks exactly like Alison. But it can't be Alison. Can it?
Sasha Pieterse portrays Alison DiLaurentis, the former queen bee whose mysterious disappearance rocked the small suburban town where she lived.
Pieterse, originally from Johannesburg, South Africa, lived in Las Vegas with her show biz parents before the family moved to Los Angeles. She became accustomed to the rigors of a career in entertainment at an early age, as her parents were a professional acrobatic dance team who performed all over the world.
When she was just four and a half years old, Pieterse met with a Los Angeles agent who quickly signed her, and she has been acting and modeling ever since. She has appeared in scores of television commercials, on billboards and booked modeling assignments throughout the country.
Pieterse got her start in television in 2002 at the age of six, starring in the WB comedy series Family Affair -- a remake of the late 1960s hit -- as Buffy, opposite Gary Cole. She was awarded a Young Artist's Award for her work on the series. She later reunited with Cole as his daughter in the cable thriller Wanted.
Pieterse's first major film role was as the Ice Princess in Robert Rodriguez's The Adventures of Shark Boy and Lava Girl 3D, with Taylor Lautner and George Lopez. She also starred in Good Luck Chuck and in the telefilm Claire, opposite Valerie Bertinelli. Pieterse recently appeared in the hit series Heroes in the recurring role of Amanda Strazzulla, a young gypsy girl with fire powers. She also guest starred in House M.D., as a terminal cancer patient who was terrified of dying without ever being kissed, and in Without a Trace, in a terrifying turn as a kidnapping victim.
When she's not out by the pool reading or hanging out with her friends, Pieterse enjoys writing and singing country music. She also designs jewelry, dances and plays racquetball and golf with her father. An only child, Pieterse calls her Pekinese Precious and her goldfish Crystal "siblings."
