Lindsay Lohan’s ex girlfriend Samantha Ronson threw a fit of rage at a party when a girl bumped into her deejay booth and spilled a drink near her turntable.

Ronson was playing at the Georgica Blue’n’Cream party in East Hampton.

She got enraged and stopped the music at 2 a.m. to give the guests a lecture on party etiquette.

“If I”m gonna play for you, I think it would be common courtesy not to spill drinks on my table,” the New York Post quoted her as saying.

“I thought this would be obvious but apparently not!” she added.
