15. Lucy Hale
Show: Pretty Little Liars
You might have seen Hale's cameo in Scream 4, but her day job is starring as Aria in the ABC Family series. Possibly the most scandalous of the quartet, Aria started hooking up with her English teacher at the same school in which her mother works. But to make it seem less illegal, Aria and teach are "truly in love."
To be fair, he didn't know she was underage when they met. OK, the more we write this, the more we feel like accomplices to a crime.
