When rapper Diddy started screaming obscenities at supermodel Naomi Campbell, he probably failed to consider one of the following possible endings for the feud: 1. Naomi will drag his ass to court and make him pay for each nasty word he said at her expense and 2. she will probably beat the crap out of him because, you see, she has 'temperamental issues'.

The famous supermodel (famous for her rough way of making herself understood by her employees) and the rapper and music producer used to be friends back in the old days. Unfortunately, they are so no more and the causes for the rift are not known. Instead, we have only speculations for what might have set them at each other's throats.

Rumor has it that Diddy's baby momma, Kim Porter (who just gave birth to twin girls a couple of weeks ago) can't stand Naomi and this might be one of the reasons for which Diddy no longer hangs with her. Then again, back when they were still friends, Diddy wanted Naomi to model for his Sean John collection but word on the street is that he wanted her to be the face of his line without getting a dime.

Whichever of the two might be the cause of their split, the point is that Diddy is still not over it. Various media outlets report that the two got into a very pretty heated argument at an after-Grammy party over the weekend, in front of all the people invited and foul words not excluded. The paradox of this alleged fight is that eyewitnesses said that the model 'played it cool', let Diddy have his say and then left the venue without even bothering to answer him.

'Diddy just started screaming at her when he saw her. No one could believe it. He was screaming obscenities at her, and also screaming at Terrence Howard, who was with her.', a source told the US media. It is yet unknown which are the 'obscenities' Diddy shouted at the model or what exactly prompted him to act this way. But he should have known by now that Miss Campbell is not the one to mess with and, even more, insult and/or provoke.
