[All photos by Kirillwashere] After a beautiful (and surprisingly sunny) day on Long Island, East Hampton was more than ready for a night of partying as the second annual Malibu Summer Soiree kicked off Saturday night at Lily Pond. Nicky Hilton, who co-hosted the first Malibu bash last summer with Samantha Ronson, returned for the second go-around to host with Absolut Mango and Perrier Jouet. While big sis Paris skipped out on the West coast to East coast trip (What? She has better things to do than vacay in the Hamptons?!) Nicky brought her boyfriend David Katzenberg along for the ride.
