River Viiperi, Paris Hilton’s boyfriend, arrested at XS nightclub in Las Vegas

It has been reported that after Paris Hilton embarked on a same-sex kiss with a fellow member of the female species, her latest boyfriend River Viiperi was later arrested for misdemeanor battery.

TMZ are claiming that the alleged victim told police that 21-year-old model River Viiperi “punched him in the face sometime around 2:30 a.m. … and injured him so badly, he needed medical attention.”

It is believed the victim is the boyfriend of the girl that Paris Hilton shared her alleged liaison with.

The incident is said to have taken place at XS nightclub inside the Encore hotel during the early hours of Monday morning.

The US website claim the victim told security he wanted to “press charges”, with law enforcers arresting River Viiperi at the scene, before he was cited and released without going to the police station.

It is also reported that Paris Hilton had left the scene by the time police arrived.

Prior to the drama, the couple had been tweeting about their vacation in Las Vegas, having seen Justin Bieber perform live at the MGM Grand, another hotel on the famous Vegas strip.

Giving a shout-out to friends, Paris Hilton, 31, wrote: “At the @JustinBieber concert at @MGMGrand with @RiverViiperi @BarronHilton [younger brother] @VanessDubasso [Barron’s girlfriend]…

“So much fun at @JustinBieber’s concert with @RiverViiperi. He’s such an amazing performer!”

River Viiperi had also been gloating, adding: “Loving it @xslasvegas with my baby @ParisHilton + crew #lovinglife.”

Paris Hilton – who has been linked to Backstreet Boy singer Nick Carter, Good Charlotte rocker Benji Madden and The Hills star Doug Reinhardt – was only linked to River Viiperi for the first time in September.
