@GS74 - There are sites devoted to celeb tattoos just like celeb feet, but I can't find any info on the angels in particular, other than they are "Rücken tattoos" - whatever that is! Some are real, some are fake, and the real ones are mostly religious:
Q: I love Pauley Perrette on NCIS. Are her tattoos real? —Sally M., Atlanta
A: Most of them are. “The spiderweb on my character’s neck and the cross on her back belong to CBS. Everything else is mine,” says the star of the hit drama (Tuesdays). “The producers wanted tattoos that were visible no matter what I was wearing.” So how much real ink does Perrette sport? “I have no idea!” laughs the actress, 44.
Online Extra: What is Pauley’s favorite tattoo?
“On the inside of my ring finger, on my left hand, I have the numbers 12:21. That’s my favorite bible verse, Romans 12:21 which is, ‘Don’t be overcome by evil, but overcome evil with good.’ That’s my favorite one and I look at it every day. That’s my mantra,” says the star.
