A seemingly innocent girl-on-girl kiss sparked big consequences for Paris Hilton and her 21-year-old beau.
Early Monday morning, Paris allegedly engaged in the same-sex lip lock at a Las Vegas nightclub with another partier.
Unfortunately, her boyfriend, River Viiperi witnessed the smooch and did not take it well, to say the least.
Reportedly, the young model punched the other girl's boyfriend, causing him to seek medical attention. Las Vegas police told Gossip Cop that "they had enough probable cause to believe a misdemeanor battery occurred.”
The pugnacious partier was cited and released "in lieu of arrest" and is required to appear in court at a later date.
