With the Pretty Little Liars season finale airing tonight, fans everywhere will be able to breathe a sigh of relief -- at least, we hope! -- when the identity of "A" is finally revealed. The mysterious character who has wreaked havoc on the Rosewood community for two seasons now is not only the show's villain, but also a culmination of the double-life led by deceased queen bee Alison DiLaurentis. As Aria, Emily, Spencer and Hanna uncover clues which lead them ever closer to "A," so, too, do they discover surprising secrets about their friend Ali. Between an alter ego known as "Vivienne Darkbloom," an unsettled debt, and a potential blackmailing of Spencer's dad, Ali certainly did damage this season, leaving a dangerous mess for her bffs to clean up.
Ali's evil and manipulative ways have got us thinking about other television mean girls, and we're betting some of these ladies could give Ms. DiLaurentis a run for her money! See our top 6 picks below.
