Kevin Connolly Punches Brandon Davis

Brandon Davis has been spending so much time with Nicky Hilton lately that its been looking more like he’s her boyfriend than Kevin Connolly is. At Paris’ bash last night, Kevin fought back. He was having a good time relaxing with friends, schmoozing, stealing kisses from Nicky and entertaining the guests, an insider said.

Then Brandon showed up, and Kev started looking a little tense and agitated. "He had a really serious look on his face and stopped socializing with everyone," the insider says. Finally Brandon made his way over to Kevin and shot off his mouth, like he always does. Not a good idea, Brandon! "Kevin exploded,” says the insider. “He punched Brandon in the face several times. Brandon totally backed down." The insider says the cops came soon after and calmed things down.
