Lady Gaga appeared, all dark locks and bleached eyebrows, and seemed inseparable from performance artist Marina Abramovic. Pouty-mouthed model Lindsey Wixson also attended in a slinky red gown, along with Winona Ryder and Alan Cumming. Meanwhile, back in Manhattan, a screening at the Cinema Society lured actresses Shailene Woodley and Zosia Mamet out into the limelight.
