BRAWL AT PARIS HILTON'S PAD

BLOATED Brandon Davis was punched in the face Thursday night by Kevin Connolly, who stars on "Entourage." After an US Weekly party at L.A. hot spot Area, Paris Hilton held an after-hours bash at her Beverly Hills home. Pamela Anderson, Courtney Love, Dave Navarro - and past Hilton conquests Paris Latsis and Stavros Niarchos - arrived with Davis, Nicky Hilton and Nicky's boyfriend, Connolly. One partier told us: "Brandon and Nicky decided to run around and call everyone a 'loser' or 'whore' - like the way other people call each other 'sweety' or 'honey'. " Connolly didn't like either word and when the oil heir wouldn't stop, Connolly "smacked him." Davis, grandson of the late oil billionaire Marvin Davis, shrieked and cursed insults, prompting Connolly to "punch him in the face two times." After the beat-down, Connolly told blogger Perez Hilton: "He just can't talk to me the way he talks to other people." Another shock came later when Hilton nemesis Lindsay Lohan and several friends crashed the party. One observer, who was shocked Lohan had invaded her enemy's lair, said, "Paris has done so many mean things to Lindsay."
