Diddy was left red-faced after being turned away from an exclusive Golden Globe Awards after-party.The rap mogul - real name Sean Combs - was reportedly fuming after turning up to the bash hosted by Creative Artists Agency (CAA) at Los Angeles Sunset Tower hotel on last Monday and being told his name was not on the list. A witness told the New York Post newspaper say Diddy became "verbally abusive and started yelling at security", who then called hotel owner Jeff Klein who "kindly asked Diddy to leave". The furious rapper shouted, "What are you going to do - call the police?" Klein replied, "Yes!", and then Diddy screamed, "Just try it - I'll spend the rest of my life hunting you down!" Diddy left shortly after the altercation, and he has allegedly now been banned from Sunset Tower. However, Diddy's representative insists it was all just a misunderstanding, saying: "Sean never said those things. He respects people's wishes and left. He went to Prince's party instead."Diddy reportedly soured his name with CAA after he flew into a rage at an assistant to CAA co-chief Bryan Lourd, who was hosting a Oscar party and hadn't invited him. A CAA representative has denied the star has been blacklisted.The rep said: "There is no ban on Diddy officially or unofficially. He just wasn't invited."
