Paris Hilton Swapped Spit With Another Chick In Sin City; BF River Viiperi Punched A Dude & Was Arrested!

What the heck?!?
So get this, Paris Hilton kissed a chick at XS nightclub in Las Vegas last night early this morning!
We’re talking full-on, hot and heavy, making the eff out!! Random passerbys being assaulted with saliva from 10 feet away!
That in itself isn’t so cray!
Paris has always been an epic party gal and Sin City brings out the, uhhh, most interesting in some people!
But you’ll NEVER believe what happened next!!
Her newish boyfriend River Viiperi FLIPPED OUT! He does not approve of hot girl-on-girl action, apparently!
River was so incensed, he punched another dude at the club!!!
We’re not sure what this other guy had to do with the sultry lesbian kiss, but he got an eye full of sexy chicks getting it on and then a mouthful of knuckle sandwich!
He required medical attention and everything!!
Paris left the scene before the cops came and cited River for misdemeanor battery!
The coppers are investigating but presently Paris isn’t being accused of any wrongdoing other than some sloppy PDA!
