On My Arm Girl

Justin Bieber was a guest on the Late Show with David Letterman last night, June 21, to promote his new album, Believe.

While on the show, Justin spoke about being eighteen, graduating high school, his new album, and his newest tattoo. Justin also performed his hit single, “Boyfriend”.

Two more videos from his interview can be found below the jump! BTW, I really like David’s reaction to Justin’s new tattoo.
