Justin Bieber was left "fuming" after a fight ruined his BRITs after party. The 'Sorry' hitmaker was celebrating a successful set and his International Male Solo Artist award at a club in London in the early hours of this morning (25.02.16), only for the party to be ruined when one of the men from his group "launched at someone from outside the group". A source said: "He came through a VVIP section in Tape at 1.35am and was escorted to a table in the VIP section near club dancers in skimpy underwear. He was not happy with photos being taken and the lights were dimmed. "A man from his VVIP group suddenly launched at someone from outside the group, which was protected by security." After the incident, the night was ruined for the 21-year-old singer and he abruptly exited the club. The insider added to the Daily Mirror newspaper: "Bieber looked fuming and the whole thing descended into chaos. Everyone was pushing and shoving. The man was dragged inside and everyone was pushed out. "Security got involved and managed to break it up. Bieber tried to carry on with his night but there was a really tense atmosphere and the club was overcrowded. He then abruptly left out of the back door."
