'Dancing With The Stars': 'Pretty Little Liars' Star And More Join Season 19 Cast

Mona from "PLL" and a "Mean Girls" star glam up Season 19.

She's danced around A's drama for years at Rosewood High, and now "Pretty Little Liars" actress Janel Parrish is going to dance for that mirrorball trophy on season 19 of "Dancing With the Stars."

The long-running show's co-hosts Tom Bergeron and Erin Andrews announced this year's cast on "Good Morning America" on Thursday (September 4), and it's a doozy -- from Parrish to erstwhile "Fresh Prince of Bel Air" star Alfonso Ribeiro to Olympian Lolo Jones, it's going to be quite a year. Check out the full line-up below:

Alfonso Ribeiro and Witney Carson

Does this mean a Carlton dance is in our future?

Sadie Robertson and Mark Ballas

Quack quack. We have a "Duck Dynasty" daughter in our midst!

Michael Waltrip and Emma Slater

Waltrip is a NASCAR person. I know nothing about this.

Lolo Jones and Keo Motsepe

Olympians have grown to be a huge part of the "Dancing" family, and we think all-star Lolo is going to be a force to be reckoned with.

Jonathan Bennett and Allison Holker

Aaron Samuels from "Mean Girls!" Could be great at dancing, proven to be bad at math.

Lea Thompson and Artem Chigvintsev

A.k.a. Lorraine McFly from "Back to the Future." Known for accidentally flirting with a younger version of her own son.

Antonio Sabato, Jr. and Cheryl Burke

Sabato is a "General Hospital" star and iconic Calvin Klein undies model. Hubba hubba.

Randy Couture and Karina Smirnoff

Couture is a six-time World Ultimate Fighting Champion. Will he fight his way to the trophy?

Janel Parrish and Val Chmerkovskiy

She may have been offed by "A," but we think doing the cha-cha with Val Chmerkovskiy is a solid consolation prize.

Tommy Chong and Peta Murgatroyd

Comedian Chong is going to put down that bong and dance.

Bethany Mota and Derek Hough

A YouTube beauty guru will tango with "Dancing"'s all-star hunk

Betsey Johnson and Tony Dovolani

A fashion icon joins the roster.

Tavis Smiley and Sharna Burgess

Smiley is a talk show host and best-selling author. Can he smile his way to victory!?
