Justin Bieber may have a reputation for being a bad boy (or rather, a reformed bad boy) but that doesn’t mean he’s mastered the ultimate party trick – shotgunning a beer.

The “What Do You Mean” singer visited Las Vegas this weekend to watch friend Floyd Mayweather’s fight, and he took time out to take part in a competition of his own. In a video uploaded to his Instagram, Bieber, 21, is seen in a shotgunning contest with friend Sam Shahidi while at a pool party in Sin City.

Unfortunately for Bieber, he wasn’t very good at shotgunning his can of Corona while his pal easily beat him in a matter of seconds.

“I lost but I didn’t go to college,” the singer captioned the video.

While he may have lost the chugging contest, his new single has earned him both critical accolades and serious Billboard chart achievements. “What Do You Mean” became the singer’s first Hot 100 No. 1 song and made him the youngest male artist to ever debut at No. 1 on the Hot 100. It was also at the top of Billboard‘s Digital Songs and Streaming Songs charts.

Bieber has been on the move quite a bit this past week. On Friday, he popped up in Santa Monica, California, to perform at the Think It Up telecast and rub elbows with Jennifer Garner and Gwyneth Paltrow. Before that, on Tuesday, Bieber partied with the Weeknd and Bella Hadid in New York City.
