Justin Bieber - Justin Bieber Ribbed By David Letterman Over New Tattoo

Justin jokingly referred to Letterman as 'gramps' as he refused to give up on the lecture, after asking him if it was the last one that he was going to get. Bieber remained non-committal, explaining that he'd got the tattoo to celebrate the important release of the album. In an attempt to get one over one him, Letterman continued, asking him if his mother approved. "Has your mother got tattoos?" he asked, at which point Bieber shook his head. He then asked "has your father got tattoos?" and his argument fell down at that point, as the 'Baby' singer said that yes, he has.

Letterman was not prepared to give it up though and finally had the last laugh, when he warned Bieber that he shouldn't get covered in murals, like the Sistine chapel. Bieber's response? "I'm not going for the Sixteenth Chapel look." Oh dear.
