Justin Bieber kind of knows how to party.
The "What Do You Mean?" singer decided to challenge his friend to a beer shotgunning contest while partying in Las Vegas over the weekend, but it seems the 21-year-old just couldn't keep up. In a video posted to Instagram, Justin loses by a long shot! His loss didn't stop him from celebrating though, as it seems finishing the beer at all was a feat for the recently legal drinker.
Don't worry. He explained in his caption why he didn't perform up to snuff. "I lost but I didn't go to college @sammy," he captioned the video. Justin has come a long way since he first mentioned drinking beer in a GQ interview when he was just 18. At the time, the "Boyfriend" singer claimed he had had a beer but never wanted to go overboard.
"For me, it's just like, I like to be in control of myself," he told the magazine in 2012. "I mean, I've had a beer, like, before...But I never get out of control."
