What happened on 23 November 2009 when Justin Bieber warmed up the audience ahead of a Taylor Swift concert?

Explanation

When Taylor Swift played at the Wembley Arena in London on 23 November 2009, Justin was warming up the audience. Before the concert, Usher had given him a pep-talk, telling him to do everything he could to win over the audience. 12,000 people attended the concert. Justin was on form and the audience loved him! But then, all of sudden, he misjudged the ramp of the stage and broke his right foot. Though he was in agony, he completed the show. Afterwards, Justin has said that these were the three longest minutes in his life. He was taken straight to hospital from the concert.
