15 Celeb Tattoos With Meanings Fans Probably Didn't Know About

At one point in time, tattoos were reserved for sailors, bikers, and other nefarious members of society. Nowadays, they've become a respected art form as well as a unique symbol of personal expression.

What might appear on the surface to be nothing more than a spontaneous passing thought, more often than not turns out to hold deep sentimental meaning.

To get a better idea of what I'm referring to, have a look below at these 15 celebrity tattoos with hidden meanings fans probably didn't know.

Justin Bieber has a tattoo on his leg that reads "Better At 70."
