Before "Pretty Little Liars," Parrish worked on many other projects. For instance, she was Jade, one of the main characters, in "Bratz." She also had a song in the movie called "Rainy Days."
She got her start in musical theater, and she has had appeared in nine movies and eight television shows. She's been featured on four soundtracks. For somebody who's just 23, that's impressive.
Parrish said that to have a successful career you have to stay busy, which is what she does. "I try to stay busy when I'm not shooting something, so I always try to have some different project lined up."
Two of her recent movie projects are now available for people to see: "4 Wedding Planners" has just been released on Netflix, iTunes and Amazon, and "Celeste and Jesse Forever" is in theaters (though none in West Virginia).
Outside of acting, Parrish likes to sing. She writes songs and can play the piano. She said right now she's focused on acting, but she would definitely consider any music opportunity that arose.
Last season "Pretty Little Liars" revealed that Mona was the first "A," the mysterious person tormenting the girls. This season, she has been in a mental hospital.
For Parrish, playing crazy Mona was scary at first. She wasn't sure how she would do it. She said the role is the most challenging and fun she's ever had.
