Justin Bieber Gets His Sixth Tattoo

David Letterman is not going to be very happy. After just lecturing the Biebs on national television about getting tattoos, JB went out and got another one. 18 year old Justin has gotten his sixth tattoo, but blink and you'll miss this one. Its the small Japanese Kanji symbol for music and it sits opposite his Believe tattoo on his left arm, which is the latest one that Letterman was scolding him about.
