Justin Bieber's encounters with his Beliebers aren't always positive, apparently.
The pop singer was attacked on stage in Dubai Sunday by a fan who was eventually detained by security, Us Weekly reports.
According to Us, Bieber was playing piano along with the song "Believe" when the male fan rushed onstage and tried to grab him. Security responded immediately, but in an attempt to get away, the superfan knocked over the piano.
"Security detained the young man," a source close to Bieber told Us. "All was fine and Justin continued the show."
The 19-year-old appears to have shrugged off the incident, tweeting after the show: "Dubai. Nothing stops the show. 2 more to go. #BELIEVEtour"
