Justin Bieber. He's beloved by fans all over the world, but he's also got a reputation for being, how do we put it, a bit of a diva.
The 22-year-old singer left the stage in Manchester after asking his fans to stay as quiet as possible when he was singing. When the fans apparently couldnt contain themselves, he walked off to loud boos from the crowd.
Even though he returned to finish the set, Bieber's behaviour didn't go down well with a lot of his fans, many of whom had paid £60 for a chance to see their idol.
This isn't the first time Bieber's lost his temper. From refusing to take pictures to the furore over his Instagram account last summer, Bieber's proven his temper can be very short indeed.
