Zayn Malik may think he's the trendsetter of the celeb world, but he's got nothing on Justin Bieber - who just revolutionised the sunglasses game during a walk through the streets of NYC with Cory Gamble.
You've been wearing your sunnies on your eyes? Amateur. Been resting them on your head when you don't need them? Ugh, that's so 2008.

And oh yeah. Again:
Also ALL of the lolz at the fact he doesn't even break stride to take that selfie with a fan. Whadda pro.
So what do you reckon then - think the chinglasses thing is going to catch on?
