Does this celebrity's tattoo look at all familiar? This creepy skull is inked on the hand of a famous R&B crooner, but it is just one of many, many tattoos on his bod.

However, this ink job has more than meets the eye -- what you actually can't see in this picture is the halo floating above the skull's head (it's blocked by his sleeve), and these symbols hold a special meaning for the entertainer.
