Lucy Hale Celebrates 15 Years of 'Pretty Little Liars' With Throwback Photos

Lucy Hale marked the 15th anniversary of Pretty Little Liars with a heartfelt Instagram post, sharing behind-the-scenes moments from the beloved series.

The show, which aired from 2010 to 2017, follows four teenage girls whose lives are upended after their friend Alison disappears, leaving them vulnerable to mysterious threats from an unknown figure known as "A."

Hale, who played Aria Montgomery, posted a carousel of throwback photos and videos, reminiscing about the experience.

“Happy 15 years to PLL—the nostalgia!!” she captioned the post, adding a shushing emoji.

And to all of you, who made this one incredible ride—thank you for keeping this alive for so many years. I know it’ll be one that people keep discovering.”
