Rosewood is getting a few new faces when "Pretty Little Liars" returns in January, according to The Hollywood Reporter. It was previously announced that Lauren Tom ("Supernatural"), Oliver Kieran Jones ("Episodes") and Anne-Marie Johnson ("Girlfriends") would be joining the cast but now we have more information on their characters.

All three ladies will make their debut in episode 21, titled "Bloody Hell." Tom landed a recurring role as Rebecca, "an attorney who gets involved with the Liars." ABC hasn't released any more details about the character but Rebecca could be defending Spencer (Troian Bellisario), who was arrested for the murder of Bethany Young.

Colin will play a handsome and charming British friend of Melissa Hastings who comes in contact with Spencer. Johnson joins "Pretty Little Liars" as Claire, "a chic pageant coordinator who comes to Rosewood looking for girls to participate in a pageant" show.

Also popping up on the show in episode 18 (titled "Oh, What Hard Luck Stories They All Hand Me") is Elizabeth McLaughlin as Leslie Stone who enters Rosewood asking questions about Spencer and the gang, according to Wetpaint.

Show creator Marlene King and the cast previously dished on the Christmas episode, airing Dec. 9, and hinted that it could be deadly for one Liar. The episode will also see Emily (Shay Mitchell), Aria (Lucy Hale), Spencer and Hanna (Ashley Benson) try to help Spencer get out of her legal mess.

Alison (Sasha Pieterse) also gets a visit from the ghost of Mona (Janel Parrish), who was killed in the summer finale.

"She's going to be the Ghost of Christmas Past, Present and Future," Parrish said. "She gets to mess with Alison - and in a fabulous costume, I might add."

"Pretty Little Liars" returns with a Christmas episode, titled "How the 'A' Stole Christmas," on Dec. 9 on ABC Family.
