Justin Bieber paid tribute to his mother, Pattie Mallette, by getting a new tattoo.

The "Baby" singer had mom's eye tattooed on the crook of his left arm, symbolically watching over him and hopefully keeping him from continuing on with his d-bag antics like peeing in mop buckets, racing his Ferrari up and down his street and spitting in peoples' faces (that last one was his bodyguard -- but, still!)

The Biebs, who got the ink between his tiger and a knight with the word "Believe" above it, had the work done by New York City artist Bang Bang, whose done work on a number of other celebrities.

Mallette, 38, opened up about her son's recent behavior on Bravo's "Watch What Happens Live," last week, telling host Andy Cohen, "I'm not naive to think that my child is perfect and making all the best decisions of his life."

"He knows what I disagree with and he knows all the things that I'm really proud of him for, too," she added. "I mean, people don't talk about all the great things he does every day. Every night before a show, he meets with Make-a-Wish kids. He goes to sick kids' hospitals. He visits with them (and) takes his time. He gives back to charities."

We lost count of Justin's inkings, but he's got a lot. So do these other ink obsessed stars.
