The hit series has been greenlit for a fourth season, ABC Family president Michael Riley said Thursday. The 24-episode season will premiere in mid-2013.
Meanwhile, ABC Family will air a "Pretty Little Liars" Halloween special Oct. 23 at 8 p.m.
The renewal is hardly surprising, as "Pretty Little Liars," which wrapped its third season Aug. 28, is the cable network's top-performing series. It also was cable's top summer show this year in multiple demographics, including viewers 12-34 (with a 2.8 rating) and females 12-34 (with a 5.0 rating).
The series, loosely based on the young-adult novels by Sara Shepard, follows a quartet of girls whose clique falls apart after the disappearance of its leader.
