Justin hit Big Apple hotspots 1Oak, Marquee and Avenue on his all night club crawl.

Though Justin's underage, the New York Post cites a State Liquor Authority as saying, "Nightclubs have the right to admit guests of any age—as long as booze is only served to people 21 and older."

As OKMagazine.com recently reported, Justin tweeted his Beliebers a picture of himself drinking a can of beer while in South Africa on tour. The country's legal drinking age is 18, so Justin was perfectly within his rights to crack open a cold one.
