There surely are so many pretty little liars going around in Rosewood. Even after five seasons of ABC Family's hit teen drama series, they still keep on coming. And there's another one showing up when  "Pretty Little Liars" returns in January. 

According to Wet Paint, a pretty little troublemaker is making her way to Rosewood when season 5B airs next year. Executive producer and showrunner Marlene King talked to E! Online and confirmed the revelation. 

"In the episode where Mona met her demise, she was talking to her friend Lesley on the phone that day and we finally get to meet Lesley. She comes to town," she said. 

So, this girl Lesley was friends with Mona so that means that she is not going to be all that bad. 

However, Wet Paint does note that there are too many characters in Rosewood to keep track of already. Adding one doesn't make sense. According to the website, it is best if the show develops the existing characters than keep adding new ones. And Lesley won't be the only addition either.  There are also other newcomers in season 5, including Lauren Tom who will play Rebecca, a lawyer who gets involved with the Liars, Oliver Kieran Jones who will play Colin, a British friend who Spencer will meet, and Anne-Marie Johnson to play Claire, a pageant coordinator who will urge the girls to join in. 

"Pretty Little Liars" is surely making the season more intense. What started out as a mystery surrounding Ali's murder will now turn into something else.  The Liars just can't seem to shake their way out of trouble and even has trouble coming to them. So, what role will Lesley play? What trouble will she create? What about the other new faces, will they cause trouble, too?  

"Pretty Little Liars" will return in Jan. 2015 on ABC Family.
