Even outside of Rosewood, the ladies of Pretty Little Liars still know how to keep us guessing.

Shay Mitchell (Emily) took to Instagram last week, posting a photo of herself with a short bob haircut. The photo caption said, "“Chop chop!!! With @davenmayeda Omg!!! Bye bye long hair!" and Shay was even holding a pair of scissors in the pic. All signs pointed to new 'do, but we should have known better, PLL fans. It turns out Shay's hair was full of secrets — she was actually rocking a trendy faux bob.

Troian Bellisario (Spencer) wore the same hairstyle last year during an appearance on Extra and Sasha Pieterse (Alison DiLaurentis) also donned the short faux ‘do in September at the premiere of Insidious: Chapter 2.

Now that we've seen both Shay and Troian show off the faux-bob, it's time to decide whose style you like the best. Check out their shorts hairdos and then sound off below!
