Kate Moss was injured by a flying chunk of ice at a nightclub on Saturday night.
The supermodel, 33, had been planning to perform a duet with fiance Pete Doherty for a friend's birthday, but she left the club after being struck on the forehead by an ice cube during a food fight.
A source told The Sun, "It was all a bit of a laugh at first. Kate thought the whole thing was hilarious. But then one chunk of ice was thrown a bit hard and hit her smack in the forehead. The bump came up immediately."
"Someone joked she should put a bit of ice on the swelling. That’s when Kate decided to leave. She went via the back door but was still photographed wearing a ridiculous bowler hat.”
