P. Diddy shouted and cursed at a nightclub host who asked him how many people were in his entourage.
The hip-hip mogul - real name Sean Combs - arrived at New York's GoldBar this week with four friends and lost his temper with a female member of staff when she didn't immediately allow him entry to the club.
A witness told the New York Post: "He walked right up to the door girl with four other people in his crew. When she asked him how many people he was with, Diddy just called her a 'f***ing b***h' and opened the velvet rope and let himself through."
Representatives for both the rapper and GoldBar refused to comment.
Meanwhile, Diddy enforced his own strict door policy at his annual White Party earlier this month. Guests - including Billy Joel's wife Katie - were turned away for breaking the strict all-white dress code.
Katie was told she could only enter the party if she exchanged her cream outfit for an all-white one, but she refused and hastily left the party with Billy.
Another reveller was forced to strip in the street, after the hip-hop star's security team made the man swap his cream trousers for a pair of snow-white slacks.
