Now we know where it is, we just don't know what it says!

Hailey Baldwin wore her hair up at her PrettyLittleThings holiday collection launch last night, and she gave us our first glimpse at the matching tattoo she got with husband Justin Bieber! Her ink runs vertically up her neck, but we can't zoom in enough to see the wording.

As we all know by now, The Biebs got his on his face! The "Sorry" crooner has been photographed with a microscopic tat above his eyebrow, but it's so small that it's barely visible to the naked eye. That's probably for the best!

Does anybody have expert vision that can decipher Hailey's for us?
