Justin Bieber rushed by fan onstage in Dubai

Justin Bieber was bum-rushed by a fan onstage at a concert in Dubai Sunday night, after the Canadian superstar was two hours late in performing for the second night in a row.

The fan ran onstage while Bieber was sitting at a piano and touched him on the back, and security quickly following, ripping the fan away from Bieber and dragging the person backstage. The piano was flipped over in the scuffle, and reportedly was unplayable for the rest of the concert.

Unfazed, Bieber continued with the show as if nothing happened, finishing the song and coming back minutes later for an encore.

The incident came a day after the Twitter account for E! News was hacked and sent out false tweets saying that Bieber had been arrested and that he told the outlet he was gay.

Bieber was also sued Sunday by two Virginia men whoallege that he stole a song from them and used it on an album he put out in2010, according to published reports. They are seeking $10 million in damages.

Bieber's rep didn't respond to a request for comment.
