[Spoiler alert: The following article contains spoilers about the most-recent season of "Pretty Little Liars."]

"Pretty Little Liars" ended season 6A by revealing the identity of "A" to be Alison DiLaurentis' (Sasha Pieterse) long-lost sister CeCe. With the biggest mystery finally solved, the show's executive producer I. Marlene King promises there is much more to come.

"I think 6B was sort of a breath of fresh air," King said at a panel at the Paley Center for Media. "There is a little more to the Jason/CeCe dating story so that's a tease...I think we have definitely save the best for last."

The biggest change to the hit show is the five-year time jump. When the series returns to ABC Family/Freeform on Jan. 12, 2016, the girls of "Pretty Little Liars" are all grown up and only return to Rosewood at the request of Alison. Four of the show's stars at the PaleyFest event agreed the jump was welcome.

Ashley Benson, who plays Hanna Marin, was thrilled to learn the girls were done with high school on the show.

"I hate being in a classroom," she said. "Being in a classroom, I want to die."

Pieterse, whose character was buried alive, was happy she her days of having dirt poured over her were over. "I just can't believe I got buried four times... I've never felt that gross before. I had dirt in my teeth."

"We all have careers now," Lucy Hale, who portrays Aria Montgomery, shared. "You get to see where we work."

Troian Bellisario, who plays Spencer Hastings, said her character changes up her style.

"I got bangs, it's epic. I'm so excited to share it with you guys," she joked.

Another change the actresses spoke about was the show's famous opening which featured Lucy Hale making a "shushing face" at the end. This time around, all the girls will have a turn at making the face which they all said proved to be very difficult to do.

"I literally was like, I'm done, I give up, don't use me," Benson said of her many failed attempts to make the perfect shushing face.

"You can't actually touch your own mouth," Hale explained.

"Shay [Mitchell] (who plays Emily Fields) is not here today but the note for her was 'less sexy, less sexy,'" King said with a laugh.

The "Pretty Little Liars" stars also said they have a difficult time filming sex scenes.

"Everything is so technical with love scenes. If your hair is flipping at the right moment...it's a little bit weird when you're filming it," Hale said.

Benson said she has a unique approach to the sexier moments.

"I like to get more awkward...well, I have to do this so I'm going to make you feel uncomfortable first," she said.

Bellisario shared some sex-scene tips.

"Just make him laugh," she advised. "I'm just like the weirdest person ever because otherwise it's so weird.

Hale agreed, "It's weird, it's weird."
