Paris Hilton continues to make bad life decisions.

While partying in Las Vegas at the XS nightclub with her current boyfriend, he was arrested for assault.

According to TMZ, a male clubgoer filed a report with the Las Vegas Metro Police Dept. claiming his girlfriend was “making out” with Paris inside XS nightclub at the Encore hotel.

Apparently, Hilton’s new boyfriend River Viiperi got upset his girl was playing tonsil hockey with someone else.

Seriously, what do you expect from a 21-year-old?

The victim told hotel security he wanted to press charges against Viiperi, so when police arrived, Viiperi was arrested.

Paris had already left the scene by the time police showed up.

She’s loyal like that.
