David Letterman Makes Fun Of Justin Bieber Justin Bieber stopped by The Late Show With David Letterman last night to promote his new album, Believe, but I’m sure it didn’t go as well as Bieber would have hoped.Letterman began by making fun of Bieber’s new tattoo, which says Believe in support of his album, by askingL “How does that help how you look to have a tattoo?”Bieber responded, “How does it not help the way I look?” and then explained that the release of his album the previous day important so he wanted to mark the occasion. Letterman then grabs Bieber’s arm attempting to wipe it off with Bieber yelling “Eh! Eh! Eh! This is brand new!”Letterman later says, “Do me a favor, don’t go nuts, you know what I mean? Because more and and more, you see the ‘mural’ and like the Sistine Chapel … it’s too much.”Bieber replies: “I’m not going for the 16th chapel.” Letterman then jokes “Canadian high school!” Justin looks abit uncomfortable and then Letterman offers up an awkward fistbump.Check out the video above!
