Mischa Barton apparently got into a fight at a Halloween party on Saturday.
The star, who was at Park Bar in New York dressed as a peacock, reportedly had a drink thrown over her by a male party-goer.
One onlooker told Bang Showbiz: “I was standing beside this guy at the bar when Mischa went past us carrying two drinks. The next thing I knew he threw his drink over her back and she turned around and asked him, ‘Did you just throw a drink over me?'”
“The man responded that the drink was in retaliation for Mischa stepping on his shoe and she threw one of her drinks in his face.”
The witness then added: “Within a few minutes one of her male friends came over to confront the guy and asked him to step outside. Mischa’s friend left but then he kept coming back every few minutes to complain.”
Apparently the incident resulted in a brawl, before two security guards threw out the drink tosser.
