If you're a fan of the Pretty Little Liarsbook series, then you'll be stoked to hear who'll be the new show's first big cameo. Guesses? Time's up... It's author Sara Shepard.
In the seventh episode, Sara will play a substitute teacher at the girls' high school and have a "friendly encounter" with one of them. Lucy Hale, who plays Aria Montgomery, is probably hoping it's her. She's obsessed with Sara's work and spills, "When I got involved in the show, I went and bought all of [the books]. I'm now on the seventh one...I can't stop reading them. They're addictive."
Standing on its own, the show is already gathering a substantial fan base. The first episode, which premiered on June 8, raked in 2.5 million viewers. In fact, 853,000 female teens watched the episode -- that's more than even Glee!
