ABC Family has renewed Pretty Little Liars for a fourth season, network president Michael Riley announced Thursday.
The new season will consist of 24 episodes and air sometime in mid-2013.
Pretty Little Liars was the No. 1 cable TV show in its time period throughout the summer across its target 18-34, 18-49 and 12-34 demos.
Pretty Little Liars will air a special Halloween-themed episode on Oct. 23, as part of the network's "13 Nights of Halloween" programming event, and then will return with the rest of season three in January 2013.
