Cheers to a new season of 'PLL'!

Pretty Little Liars
is getting a maturity makeover!

With PLL's highly-anticipated time jump just less than a week away, we're desperately waiting to be re-introduced to the older version of our favorite Rosewood residents.

After that answer-packed summer finale, fans will now be transported five years into the future where a new big bad is waiting to take text message tormenting to a whole new-- and much more deadly! -- level of craziness.

To help get your heart pounding even harder for Tuesday's winter premiere, ETonline has your exclusive scoop straight from the five Liars about new secrets, "mature" situations, and how the time jump has revolutionized the show.

So what can fans expect when Aria, Hanna, Emily, Spencer and Alison reunite in Tuesday's all-new episode?

"We have new secrets from each other," Troian Bellisario teases. "So the really exciting thing is to get to watch who these people are now, and how they interact now that five years have gone by -- and a lot of stuff has happened in those five years."

One of the most exciting things that has happened over the five-year fast-forward is the fact that the girls have all turned 21, which means it's finally time for time to have some pretty little drinks!

"It's nice to have mature conversations out of a high school setting," Ashley Benson says of the Liars' happy hour-infused season.

"It's so funny because the writers have us drinking in almost every scene to show that we're age-appropriate," she adds with a laugh. "But it's been fun! I think all of us have had a really good time and it's fun to develop a new sense of the character."

Shay Mitchell
, agrees with her ButtahBenzo bestie, saying, "It's just fun to have different sets and be able to act like we do outside of the set, which is a little bit more mature, a little bit older, a little bit wiser so I was really excited for it."

Not only has it been fun for the actresses to explore new facets of their characters, but this means that the fans will be able to tune into a completely revamped show.

"I think for the viewers it's also awesome because a lot of the viewers started [watching] pretty young and they've grown up with the show," Sasha Pieterse explains. "And now, they get to be going through the same things that [the Liars] are going through so I think it's really great and relateable for those viewers."

"Obviously the show is still going to have the heart of it, which is the friendship between these four girls," Lucy Hale assures the fans. "They've gone away for five years… but what's still so great is that they're still there for each other and they still love each other."

But if you think this new season is just going to be cocktails and re-connections, then you clearly don't know PLL!

"The chaos still continues," Hale spills. "We're still going to have that drama and all the cliffhangers and everything, but we’re going to get to see how these girls have grown up and how they’ve evolved and what kind of jobs they have and their relationships. There's new relationships and we're introducing new characters."

Hale continues, "So we still have what made the show popular in the beginning, but it has gone a different path which is something fresh and new. I think that the people that watched in the beginning are going to still continue to tune in, but I think we'll actually maybe get some new viewers too because they're going to see that we've grown up a little bit."

Tune into the winter premiere of Pretty Little Liars on Tuesday, Jan 12 at 8 p.m. ET/PT on Freeform, the new name for ABC Family.
