Justin Bieber Slams Prince William’s Hair With ‘Propecia’ Joke

Justin Bieber is just a normal teenager.

However, his sense of humor has gotten him in trouble with U.K. citizens. In a interview with Rollercoaster magazine, Biebs made an innocent comment on Prince William’s thinning hair.

“I mean, there are things to prevent that nowadays, like Propecia,” Bieber, 18, told the U.K.’s Rollercoaster magazine about the 30-year-old royal’s thinning hair. “I don’t know why he doesn’t just get those things, those products. You just take Propecia and your hair grows back. Have you not got it over here?”

Obviously, Justin was just poking fun but his “Propecia” crack is not fairing too well with the Brits.

Will he apologize? Is Prince William offended?
