Camille Grammer Former BF -- She's a Violent Fame Whore

Camille Grammer's former boyfriend has fired back at allegations he beat her ... claiming the night things fell apart she flew into a rage and snapped when he called her a fame whore.

Dimitri Charalambopoulos just filed legal docs, with a radically different version of events from Camille. After returning to her Houston, TX hotel after a medical procedure in October, Dimitri claims he got on his cell phone at 11:30 PM to call a male friend about arranging airport transportation.

Later that night, as he lay sleeping, he claims Camille woke him up, screaming he was a liar and a cheater and that the call was from a woman. He says she then grabbed his phone, threatened to flush it down the toilet and then snapped it in half.

Dimitri says she then began hitting him and he held his hands up in self defense.

Now the juice ... he says, "I told her that I now knew why Kelsey left her, because she was a 'fame whore' that only cared about attention and money."
