Guests lists at industry parties are a tricky matter, and their convoluted politics become even more complex when one's throwing an exclusive post-awards show orgy, as hosts try to balance the ratio of talent to the behind-the-scenes types hoping to fellate them: invite too many famous faces and they might end up wandering the party looking vaguely lost, frustrated as seemingly every eager reveler is already engaged in the act of servicing someone else; invite too few, and guests will mob the talent, greedily clawing at the overattended VIPs for some celebrity-pampering time. Things become more tangled still when personal histories are involved, and the defiant uninvited show up, determined to test the superhuman power of fame over velvet rope and clipboard, as demonstrated by today's Page Six item about an alleged confrontation between Sean "Still Diddy This Month" Combs and the CAA gatekeepers trying to keep the boldface interloper out of their post-Globes party at the Sunset Tower:

When Diddy became "verbally abusive and started yelling at security," said one witness, hotel owner Jeff Klein came out and "kindly asked Puffy to leave." Combs shouted, "What are you going to do - call the police?" Klein said, "

Yes!" Combs shouted back, "Just try it - I'll spend the rest of my life hunting you down!" But he left soon after. A source claims Combs has been blacklisted from CAA parties since an incident years ago when he lost his temper with an assistant to CAA co-chief Bryan Lourd, who was hosting an Oscar party. "He showed up uninvited and threw a fit when he wasn't let in," a source said. "He wasn't invited then, either." Combs is now said to be banned from the Sunset Tower. A CAA rep said, "There is no ban on Puffy officially or unofficially. He just wasn't invited."

Going unreported is Diddy's less confrontational attempt to gain entrance to the event by offering a plump, juicy baby, freshly abducted from the Cedars Sinai nursery, to the hosts; while the infant's scent quickly wafted into the party and drew to the door of the venue a throng of CAA staffers reflexively salivating at the prospect of soon sinking cocktail toothpicks into its supple flesh, the bribe was summarily rejected, prompting the regrettable, angry words.
