This is the kind of treatment Justin Bieber is definitely not used to – the heartthrob was on the receiving end of a tackle by an unidentified man during an appearance at Macy’s Herald Square in New York City. The incident happened when Bieber who was at the giant superstore to debut his new perfume “Someday” went outside to greet fans who hadn’t made it into the unveiling. According to witnesses, when the singer exited the doors, the man leaped over a metal barrier and knocked him to the ground. Bieber appeared uninjured but very shaken up.
