At the Cinema Society's screening of The Good Night, in East Hampton on Saturday, celebrities had dreams on their minds. That's because Jake Paltrow's film is all about them; the hero even falls in love with a girl who exists solely in his sleep. The part of said lass is played by Paltrow's sister, Gwyneth, who showed up at the party and mingled with East End A-listers like Bob Balaban, Billy Joel, Stella McCartney, Donna Karan, and Ed Burns. "I actually keep a dream diary," Christie Brinkley told Daily Intel. "I actually created a dream club, where we'd all get together and tell each other out dreams." Wait, really? "Oh, it was way back in the day when I used to be on tour with Billy [Joel]'s band, so we would all get together for dream clubs." Mm. Touring with a rock band doesn't sound quite like we imagined it. —Alex Gartenfeld
