and Nicky Hilton
hit the town Friday night for a double date with boyfriends Cy Waits
and David Katzenberg
. The foursome dined at Hollywood's Cleo at the Redbury, sharing Mediterranean specialties like Htipiti and baba ganoush dips with flatbreads. Though Paris's paparazzi-shy boyfriend slipped in and out the side entrance, the camera-ready heiresses arrived at the restaurant's front door.
