"This is a perfect example of what we do on set – I don't know how I am so lucky," says Troian Bellisario, who plays Spencer Hastings (far left). "Pictured to my right are some of the best actresses I know, and they are also the coolest girls on the block. Also pictured: a cronut. Pinch me."
Janel Parrish, who stars as Mona Vanderwaal, has her makeup done by Cindy Miguens.
"Troian and Shay look cozy on the couch," says producer Marlene King, "but this scene was no picnic. It's a finale moment worthy of big finale emotions. There wasn't a dry eye on set after this take."
"You never know where they are going to put the mic pack," says Shay Mitchell. "Hopefully it’s not freezing cold!"
"Let me introduce you to my best friend, my coat. Sets are basically like meat freezers, because the crew gets hot working under the hot lights. If they are cold, they get to wear a coat. But me? I'm usually wearing some really tiny dress or skirt. So in between shooting, I basically live in a sleeping bag."
Sasha Pieterse studies her lines in-between takes. "I'm keeping my head in the game," she says.
"This is our favorite hangout," says Lucy Hale (right). "It's unbelievably comfortable!"

"After four seasons, I finally got my own cell phone!" –Ashley Benson
"In this scene, they had a bunch of cookies as props," says Lucy Hale. "And we all took advantage of that."
"We've mastered the 'scared' look," says Shay Mitchell.
"Jordan Keslow marks scene 59 of episode 424, the season finale," says producer Marlene King. "I directed this episode, and it answers questions that the fans have been asking since the pilot."
"Our wall of A's has grown over the years," says Brant Daugherty. "You might see these in the background once in a while if you look closely."
"I am most definitely catching up on the last season of Breaking Bad in this photo" – Lucy Hale
"Us liars getting a little pretty…see what I did there?" – Ashley Benson
"Shari Perry is doing my hair. She's the best – I adore her," says Troian Bellisario. "Hair is the number one priority on our show – sometimes it really seems that way – so Shari is always curling and fluffing. I'm always trying to run away, but she always catches me and makes me look great."
Troian and co-star Janel Parrish put in a long day on set.
Sasha Pieterse maintains focus while the glam squad gets to work.
"Ash and I demonstrate our love for our iPhones here," says Lucy Hale. "I'm probably texting my mom. I talk to her all day, everyday."
"Jeff Haddad, PLL's sound mixer, hears all the secrets on set," says Marlene King. "Only two can keep a secret if. . ."
"Mona looks like she's up to no good here," says Janel Parrish.
"The Dancing with the Stars crew came to visit me on set," says Brant Daugherty, who plays Noel Kahn. "We didn't have enough time to rehearse our Foxtrot that day, so I had to go over my steps between takes. When you finally see the scene we were shooting, you'll know how ridiculous that looked."
"In our spare time, we're a Spice Girls tribute band," says Ashley Benson.
"I like to pretend I run the show," says Troian Bellisario. "Maybe one day I will. Just don't tell Marlene!"
"Buttah Benzo shows Brant and Peta how it’s done," says Shay Mitchell.
"Paula, our script supervisor, teaches me how to read her notes," says Troian Bellisario. "I'm hopelessly lost but doing a good job of pretending. Seriously, it looks like hieroglyphics. . . "
"It's a little know fact that I actually live on set," says Ashley Benson.
Who runs the world? Girls.
