Ostensibly, it’s in honor of Vanity Fair editor Graydon Carter. (Even though Barry’s IAC is wasting money backing Tina Brown’s sagging website.) So Hollywood was wondering if Barry Diller’s annual luncheon sur l’herbe nikkioscarsml2.JPGat his Beverly Hills mansion on the Saturday afternoon before the Oscars was back on this year. I can tell you it is, after a one-year hiatus because of the writers strike, and the invitations are going out now. Sure, it’s the ultimate mogul meet’n’greet. But Barry’s luncheon sur l’herbe is also where has-been celebs find refuge. Because the really hot stars will be at Film Independent’s Spirit Awards.
