Come on now, Biebs! Lay off the ink!

Justin Bieber, 18, headed back to his favorite tattoo parlor in L.A. to add to his already extensive tattoo collection. Looks like this one is going on the upper right side of his chest.

The "Baby" singer, who recently split from girlfriend Selena Gomez, has the following tattoos already: a logo for the Stratford Cullitons, the word Believe, an image of Jesus, praying hands, an owl, the Japanese symbol for music ... and a crown on his right collarbone.

Sounds like a Travis Barker in the making!
