Entertainment Justin Bieber never wears the same underwear twice By WILL MENDELSON email@example.com May 21, 2015 5:54 PM Print Share fbShare Tweet Email This is what we call a Justin Bieber problem. On Wednesday night, Bieber, 21, appeared on CBS's "Late Late Show with James Corden" and revealed that he only wears underwear once. Well, sort of. Let me clarify. Corden, 36, drove Bieber around Los Angeles and asked him about his Calvin Klein underwear ads. In response, Bieber said, "Yeah, I definitely don't wear them twice. There's so many!" I mean, I wish I had that problem, Biebs. By WILL MENDELSON firstname.lastname@example.org Share on Facebook Share on Twitter Comments We're revamping our Comments section.
