Justin Bieber Stops by "Late Show with David Letterman"

Facebook.com/JustinBieberJustin Bieber's non-stop promotional tour of his new album, Believe, brought him to CBS' Late Show with David Letterman on Thursday night.

David Letterman made Justin feel a little uncomfortable at times during the interview with his dry sense of humor, especially when he lectured the Biebs about his latest tattoo: the word "Believe" on his arm. Letterman wondered aloud, "How does that help your look?" He then grabbed Justin's arm, at which point the pop star yelled "Hey!" multiple times and declared, "This is brand-new!"

Before Justin's performance of "Boyfriend" later in the show, Letterman apologized for his actions. Justin reassured him that the tattoo was not damaged.

During the interview segment, Letterman expressed mock disappointment that Justin won't be able to vote in the upcoming U.S. presidential election because he's a Canadian citizen. When Letterman asked Justin which candidate he prefers, Justin didn't answer the question, partly because Letterman interrupted and reminded him that he wouldn't be able to cast his vote anyway.

After Letterman congratulated Justin on graduating high school earlier this year, Justin said he has no plans at this time to attend college because he's too busy with his career.
