Justin Bieber was recently booed at his concert in London. I know!! Say it isn't so. Anyway one audience member says. "I was at the concert and he [Bieber] came out at 10:15 p.m. and Carly Rae Jepsen finished her set at 9:10 p.m.. Justin should have been out at 9:30. Everyone was kept waiting not knowing anything. All they did was kept playing Michael Jackson songs. All the fans were getting so annoyed at around 9:50 p.m., fans started booing." Read more HERE.
