(Cover) - EN Showbiz - Kris Humphries and Jersey Shore star Vinny Guadagnino are said to have struck up a firm friendship.

Kim Kardashian's husband and the reality show party guy enjoyed a "boys night out" on Tuesday at STK in Los Angeles.

The pair "seemed to be in good spirits," a source told Us Weekly but it will do little to quell reports that Kim is unhappy with Kris's increasing partying lifestyle.

Kris and Vinny flew together on a flight from New York to Las Vegas earlier this month. Kris was joined by his wife on that occasion but she did not make small talk on the plane.

"Kim slept the entire time while [Vinny and Kris] chatted the whole way," an eyewitness told the publication.

A source also claims that Kim is not happy that her husband of two months has not been working since the NBA lockout and is not doing anything worthwhile until the basketball industry gets up and running again.

"She told him he needs to do something productive," a source close to the couple said. "He needs to get off his ass like yesterday." (C) Cover Media
