He has an ink obsession!

Justin Bieber just got another tattoo, and at this rate he will be as tatted as Lil' Wayne in no time!

The Canadian pop star added a koi carp, which is thought to bring good luck, to his arm right below the owl he got six months ago. His new design is his 12th piece of body art!

The other pieces of his collection include a large cross representing the letter Chi, the word "Believe", an Indian head logo, a picture of Jesus, and a crown among others.

The "Boyfriend" singer got his first etching of a seagull on his hip at the tender age of sixteen.

Now that he's rumored to be back with Selena Gomez, we wonder if a SG tat is next?!
