Justin Bieber's Sao Paulo Show Cut Short After Water Bottle Attack

Justin Bieber reportedly cut his concert in Sao Paulo, Brazil short this weekend after being hit with an object thrown from the crowd.
Bieber was performing in the Brazilian metropolis when a member of the audience threw what is reported to be a water bottle at him. Video of the incident can be seen above.
According to reports, fans waited close to an hour for the pop prince to return to the stage and finish the show, but he never did so, ending the gig without notice. (It should be noted that "Boyfriend," the song Bieber was finishing when the bottle was thrown, is often part of his encore anyway; he may have just been done with the show.)
For his part, Bieber commented on the performance on Twitter that night, avoiding mention of the drama and telling fans that it is "all love."
This isn't the first time that Bieber has been attacked onstage. Check out his earlier incident and similar moments from other artists below.
