Watch now! Janel Parrish talks about her new love interest on “Pretty Little Liars”

Mona, Mona, Mona.

The Pretty Little Liars troublemaker (played by Janel Parrish), who was once a resident of the Radley Sanitarium, has helped “A” terrorize our favorite Liars in multiple ways and yet still would love to be besties with Emily, Aria, Hanna and Spencer, is probably one of the more complicated ladies on the show, which probably explains why we can’t stop watching her. (Plus, aren’t the bad girls always the hottest?)

As new episodes continue to air, how have things changed for Mona now that we know the long-thought-dead Alison is among the living? What could she be stirring up with fellow baddie Ezra? And what famous songs is theater-trained Parrish singing when she’s away from Rosewood?

AfterEllen sat down with the vivacious Parrish at the Television Critics Association to find out all that and more.

Pretty Little Liars airs Tuesdays at 8 p.m. on ABC Family.
