Appearing on the show to promote his new CD “Believe,” Letterman grilled the young Bieber on his decision to get some ink done.
“Honestly, how does that help how you look to have a tattoo?” Letterman asked.
Bieber replied, “How does it not? It doesn’t not help the way I look.”
The exchange then got physical when the Letterman grabbed at Justin’s arm, but Beiber took it all in stride, dismissing Letterman’s crotchety lecture with a lighthearted “Grandpas.”
He also promised that he wouldn’t get so many tattoos that his arms would start to look like the “Sixteen Chapel.”
