Can you guess this TV cast by their finger tattoo selfie?

It's no secret that celebrities are huge fans of tattoos

(Seriously. It's more difficult to name a celebrity who doesn't have a tattoo.) 

Many A-listers get tatted *just* so they can show 'em off. But on rare occasions, celebrities decide to get a special "hidden" tattoo that's for their eyes only. 

Fans are lucky if they get even a glimpse at the tiny tat. (Which, I guess, is mission accomplished?)

Here are 27 hidden celebrity tattoos that are so small you might just miss 'em.
