THROWBACK: Watch the Cast of Pretty Little Liars Surprise Ally Ali on GMA!

Got a secret can you keep it?! The iconic drama series that is Pretty Little Liars came out 15 YEARS AGO YESTERDAY!

Now, I was the biggest fan of this show, making Pretty Little Liars halloween pumpkins, easter eggs, decorated my house for every season premiere/finale, and so much more. But the best moment had to be when the cast SURPRISED ME on Good Morning America before the show ended in 2017! Watch the moment below!
