Laura Leighton (born July 24, 1968) is an American actress. She is best known for the role of Sydney Andrews on the television series Melrose Place (1993–97) and its remake (2009–10) and for Ashley Marin on ABC Family's series Pretty Little Liars (2010–2017).
In the early 1990s, she took her first major acting role as Sydney Andrews in the primetime soap opera Melrose Place. The part was originally intended for only two episodes in season 1, but was developed into a full-time role for the subsequent seasons 2 to 5 (1993–97). Her character is considered one of the most beloved characters of Melrose Place and Leighton appeared on numerous magazine covers (including Entertainment Weekly and Rolling Stone) at the height of the show's popularity. However, Leighton left the show at the end of the fifth season in 1997, which saw her character Sydney getting struck and seemingly killed by a car, only moments after her wedding to Craig Field.
