Pretty Little Liars Renewed for a Fourth Season

Pretty Little Liars—the ABC Family drama based, in part, on a series of novels by Sara Shepard (what up, Downingtown?) has been renewed for a fourth season. For those of you not hip to the goings-on of the ABC Family channel, Pretty Little Liars follows a group of teen girls growing up on the Main Line who have to deal with a stalker known as “A” after their “queen bee” (Rachel McAdams in Mean Girls turns up dead).
