Adrien Grenier has scores of beautiful women at his disposal, so why does he keep hooking up with Paris Hilton? Sources close to the duo, who have been filming a documentary on celebrity and paparazzi in Malibu, have long maintained "they're just friends. Adrien met Paris when Kevin [Connolly] was dating Nicky Hilton. There's nothing there." Perhaps those sources should've been at Noir Bar in Las Vegas Saturday night, where witnesses say Paris was "grinding as hard as she could on Adrien's lap."
Eyewitnesses tell Radar that, while the Entourage hottie and the ex-con billionheiress came separately, it wasn't long before a dress-clad Hilton climbed atop Grenier's lap on a couch and began "gyrating hard back and forth. She looked completely incoherent and just kept nibbling on his ear every time she'd rock forward."
Clearly the actor felt the eyes of the room glued to his worked-over crotch, and he kept his hands in view at all times. "He did have a shit-eating grin plastered across his face, though," said another spy. "She was obviously more into him. He's been a little put off." It didn't stop the two from eventually kissing in the hallway, and Paris pulling him out of the club by the hand.
Left-coast witnesses report this isn't the first romantic rendezvous for the pair. "When Paris rented her Malibu house this summer, and Adrien was filming his documentary, they'd go down to the beach, shoot a bit, then go back up to her house," and then head upstairs, presumably to hook up. "He didn't look so hesitant then."
