I unconditionally love Justin Bieber. I mean, I’ve stuck by him while he’s playing Fast & Furious with the paps, dealing with paternity tests, and this is all while he’s wearing ridiculous outfits.

Like, get a belt kid.

Anyway, I stick by him, but there is one line he can cross: making fun of my future brother in law’s thinning hair.

“I mean, there are things to prevent that nowadays, like Propecia,” Bieber, 18, told the U.K.’sRollercoaster 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?”

What a little asshole! Not everyone has hair like the Biebs, and he needs to realize this and cool it with the insults regarding hair follicles.

Now I’m self-conscious about my hair, because if he saw the top knot on top of my head (and I literally mean knot— I’m afraid to put a brush through it) he’d never be my friend.

For the first time in my life, I’m disappointed in Biebs. (But it’s nothing another Christmas album can’t fix)
