Justin Bieber Attacked By Fan Onstage at Dubai Concert

That was close! Justin Bieber was attacked by an overzealous fan at his show in Dubai on Sunday, May 5, but luckily for the singer, security guards were on-hand and quickly tackled the fan before he could disrupt the show too much.

"A man ran on stage during 'Believe' and tried to grab Justin and knocked the piano over," a source close to the 19-year-old pop star tells Us Weekly of the incident. "He was a fan. Security detained the young man. All was fine and Justin continued the show."
