Kevin Connolly must have had a premonition when he popped Brandon Davis in the puss recently. Since Nicky Hilton and Kevin split up, Brandon has oozed himself into becoming her constant companion.They were together at Xenii over the weekend and at Area on Monday night. A friend evaluated the Brandon/Nicky liaison: “They’re friends with benefits. Sex without strings. They grew up together so they have a lot in common and know each other well. Neither of them wants a relationship now -and they don’t have to go home alone.” Most unappetizing is the fact that Nicky’s sister Paris seems to have had this SAME arrangement with Brandon just a few weeks ago- between boyfriends! It’s almost too nauseating to contemplate.
