The 'Mean Girls' actress, who has been feuding with the socialite for months, claims Paris struck her for no reason at a house party held by a mutual friend in Los Angeles.
Lindsay, 20, made the allegation to a film camera crew waiting for her outside a Los Angeles hotel. She even showed them a bruise on her left arm which she claims was caused by Paris.
She told X17: "I'm saying this on tape. She hit me for no apparent reason at my friend's house. I didn't know she would be there and she hit me with a drink and poured it all over me. It hurts and it's not OK.
"I'm sorry for everyone who thinks I'm crazy but I'm just trying to act."
It has been confirmed that Paris did attend the bash with new friend Britney Spears, but her representative Elliot Mintz has vehemently denied she hit Lindsay.
