Justin Bieber’s new Japanese tattoo

Justin Bieber has added to his growing collection of tattoos, and this one in a foreign language (no, it's not Inuit).

The 18-year-old Canuck has gotten the inner part of his right arm inked with the Japanese symbol for music, a tat that appears to be indelible (his rep did not return the Juice's request for comment). So, if David Letterman tries to rub this one away, he won't have much luck.

Biebs appears to have had himself branded in late June or early July. The last time he was photographed with a clean right arm was on Jay Leno's "Tonight Show" on June 27. But by the Teen Choice Awards last Sunday night, the young singer was photographed with his brand-new body art.

The London native seems to have ramped up his body-art collecting, having just gotten "Believe" inked on his left arm to celebrate his third album of the same name having been released on July 19.

Bieber has four other tattoos, including a praying hand on his left leg, near a tattoo of Jesus's face, and the Hebrew word for Jesus on his rib cage. At the tender age of 16, he got his first tattoo: a bird on his hip to match his dad's, paying homage to the book "Jonathan Livingston Seagull."

Having just won four trophies at the Teen Choice Awards, Biebs could be ready for another!
