Watch Justin Bieber Attempt to Shotgun a Corona in Las Vegas

So college

Justin Bieber, a 21-year-old pop star in the middle of staging a comeback, shotgunned a Corona in Vegas before the Floyd Mayweather fight last night like a college freshman on his first day of new student orientation. TMZ captured video of the momentous occasion, and it’s worth watching just to see the pained look on Bieber’s face as he chugs and chugs, all the while wearing a large brown hat that totally looks cool and not ridiculous.
