Shay Mitchell: It's Hard to Keep 'PLL' Secrets!

Pretty Little Liars star Shay Mitchell stopped by the ET offices in Los Angeles on Tuesday to chat about her hit ABC Family show, where she admitted that it's hard even for her to keep the show's juicy secrets!

"We have to be very careful and I think because there's such huge things that we could let loose -- like for other seasons when they're like, 'Who's A?' and when Mona was found to be part of the A team -- that was one where I always had to be careful answering questions," she recalls. "We get our scripts usually about a day or two before we start shooting them -- so, not that much time -- which I kind of prefer so I don't have to keep that secret for a long time."

As for why Pretty Little Liars remains such a massive hit, Shay credits the show's broad appeal.

"I think honestly because there's so many different -- you know, [the show is] funny at times, but also very dramatic," she muses. "And there's a mystery element of course, which everyone is always trying to solve it and figure out the puzzle piece. But it just takes you on a ride. Every episode, you never know what's going to happen next and that's what keeps the viewers coming back for more. But it's also very relatable ... the relationships are real and genuine, and I think that's what the fans appreciate."
