So, there I was, binge-watching Pretty Little Liars for the millionth time (don't judge, it's a guilty pleasure), and I found myself wondering, "How old was Sasha Pieterse when she started playing Alison DiLaurentis?" I mean, the girl aged like fine wine throughout the series, but I was curious to know her real-life timeline.

Sasha's Early Start

Let's rewind to the year 2010, when the first season of Pretty Little Liars aired. Sasha was just a baby-faced 13-year-old, fresh from playing young Sarah Michelle Gellar in Buffy the Vampire Slayer. She was barely a teenager, but she had already racked up quite a resume, including roles in Good Luck Charlie and Family Guy.

Now, you might be thinking, "Wow, she was just a kid!" And you're right. But remember, in the world of acting, kids often play characters older than themselves. So, while Sasha was a teen in real life, her Pretty Little Liars character, Alison, was supposed to be around 16 or 17.

Growing Up on Screen

Fast forward seven seasons, and we're at the series finale in 2017. Sasha is now a grown woman, turning 21 that very year. She had spent almost her entire teenage years playing Alison, watching her character grow, change, and even come back from the dead (spoiler alert!).

And let's not forget the iconic "A" reveal. I still remember the collective gasp when we found out Alison was "A" (or at least one of them). Sasha's performance was so convincing, it's hard to believe she was still a teenager when she filmed those scenes.

Sasha's Post-PLL Life

After Pretty Little Liars, Sasha went on to star in the Freeform series Shadowhunters and even competed in Dancing with the Stars. She's also been open about her struggles with hypothyroidism, using her platform to raise awareness about the condition.

So, there you have it, folks. Sasha Pieterse was just a young teen when she started playing Alison DiLaurentis. It's amazing to see how much she grew, both as an actress and a person, throughout the series. Now, if you'll excuse me, I have some more episodes to catch up on.
