Justin arrived at the newly opened Omnia nightclub after 1 am as a throng of fans waited to greet him upon his entrance. Donning a white jacket, the Biebs posed for photos before entering the club and heading straight to the DJ booth.

"Who's drunk tonight," he asked, before introducing famed DJ Matin Garrix to the crowd. "Where my single ladies tonight? Where are all the dudes trying to get some single ladies tonight?"

Afterward, Justin was presented with a cake in the shape of his newly acquired Lincoln Continental. Later, he proceeded to the nightclub's exclusive Heart Of Omnia area, where he sipped on Grey Goose vodka and danced at his VIP table until after 3 am.

Again, Justin Bieber is now of legal drinking age, begging the question: Do you feel old yet?
