We're used to seeing Sasha Pieterse (Alison DiLaurentis) with long blond locks on Pretty Little Liars, but the sun-kissed actress made us do a double take with her short 'do on the red carpet recently. Even in real life, this girl knows how to keep us on our toes!

On September 10, Sasha stepped out for the premiere of FilmDistrict's Insidious: Chapter 2 in Universal City, California, and the Pretty Little Liars star debuted a brand new above-the-shoulder hairstyle. But before we go calling all of our pretty little besties, we're thinking that Sasha' hair is simply pinned up to look short.

After all, her PLL co-stars Troian Bellisario (Spencer) and Shay Mitchell (Emily) have also donned the pinned-up hairdo, with Troian rocking it on Extra last year and Shay sporting the look during New York Fashion Week in February.

Check out the photo of Sasha below and let us know what you think of her chic bob in the comments!
