Sadly, not everyone can be blessed with luscious, Justin Bieber-like locks -- a reality the Biebs himself seems unable to come to terms with. The Canadian crooner, whose once-enviable bangs, with a single swoop, catapulted him to the A-list, felt compelled to pass along some "advice" to Prince William in a recent interview.
"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?"
Not surprisingly, Brits are taking the "Boyfriend" singer's careless remark about their future King as a national affront.
U.K. citizens "are viewing Justin Bieber's diss about Prince William's challenging hair problem in the same way you view an annoying fly buzzing around you. He needs to be swatted away," British journalist Jessica Callan told The Huffington Post. "Wills and Prince Harry may joke about William's thinning hair, but that doesn't mean a kid like Justin can come sauntering in and join in the joke."
