Justin Bieber said it best on his Twitter page: "New York. Wild Day."

The 17-year-old heartthrob inadvertently caused a melee in Manhattan during an appearance at Macy's on Thursday, when he was promoting his new fragrance, Someday.

When the international superstar wanted to go outside and greet his adoring public, police said they set up a small area in which he could do so. Bieber wound up walking out of the area, however, and headed towards a barricade that was holding back an estimated 500 fans. As he drew nearer, the barricade came crashing down and a ruckus ensued.
