Matching mugshots for the mantel?

Paris Hilton’s latest beau, Spanish model River Viiperi, was arrested Monday morning for allegedly punching someone at a Las Vegas club.

At around 2:30 a.m. Monday morning, Viiperi, 21, was angered when the alleged victim’s girlfriend began making out with Hilton. Apparently not a fan of the girl-on-girl love fest, Viiperi took it out on the boyfriend, allegedly punching him so hard he needed medical attention.

According to TMZ, the incident took place at the Encore hotel’s XS nightclub.

The alleged victim told hotel security he wanted to press charges against Viiperi, and when Vegas Metro arrived, the male model was arrested and charged with misdemeanor battery. However, Viiperi was never actually taken to jail, but cited and released before ever having to spend any time behind bars.

Hilton, 31, was not said to be involved in the incident and was not charged.

Welcome to the tabloids, Viiperi.
