Paris Hilton partied at the Polaroid Beach House party earlier this week, a star-studded event. The guest list included a lot of Hollywood hotties, but – of all people – Paris chose to make out with Entourage star Adrian Grenier. He’s the one with the curly hair and somewhat pudgy face. The HBO star must have done something right – but it certainly wasn’t his hairdo that won the famous heiress over. Perhaps he used a line her learned from his cable show? Grenier’s co-star Kevin Connolly previously dated Nicky Hilton, a relationship that ended at Hilton’s insistence. Brandon Davis and Brian Grazer were also at the party, among others.
