Paris Hilton kissed a girl in a Las Vegas nightclub, early Monday morning (October 1, 2012). The jury is out on whether or not she liked it but we don’t think she would have liked the fight that broke out as a result of her alleged lesbian flirtation. According to TMZ, Paris Hilton’s boyfriend River Viiperi clashed with the boyfriend of the girl with whom Paris was locking lips and a brawl ensued in the XS nightclub at the Encore hotel.

Viiperi allegedly punched the girl’s boyfriend – a 21 year-old male model – at around 2:30am and injured him so badly that he required medical attention. The police were called to the club and by the time they arrived, Miss Hilton had already scarpered but her boyfriend was arrested for misdemeanour battery. He was cited at the scene and released without being taken to the police station. It’s not a great start to River and Paris’s relationship; the pair haven’t been dating very long and clearly haven’t had that all-important conversation about whether or not its OK to kiss other people when you’re out in a club together.

The Las Vegas Metro Police Department have told TMZ that the matter is under investigation. Paris’ representatives have not commented on the situation so there’s no confirmation from Paris that she was, indeed, kissing a girl in the club. Paris has “not been accused of any wrongdoing”… at least, not by the cops.
