Justin Bieber booed at a concert?!? Now we've heard everything.
That's what allegedly went down last night at London's O2 Arena, according to multiple sources, as Justin was scheduled to take the stage at 8:30 p.m.
Instead, he didn't start his set until 10:30 p.m.
Upon his arrival, Bieber heard anything but cat calls from this in attendance, as one summed up the evening on Twitter:
"Lots of unhappy parents on a school night, but feel sorry for little kids crying because they missed half concert."
Bieber reportedly cut his set short due to time constraints, as well.
This incident is the latest in what has been a tumultuous week for the singer.
His 19th birthday was ruined when his entourage got into it with nightclub security and Olivia Wilde told Bieber to wear a shirt more often.
