NATALIE PORTMAN DRESSES DIOR: Natalie Portman, named a new face of Parfums Christian Dior earlier this week, is already showing loyalty toward the French brand. Attending a ceremony honoring Mike Nichols at Sony Studios in Los Angeles on Thursday night, Portman wore a short guipure lace dress in pale rose from Dior’s cruise 2011 collection by John Galliano. The collection was shown recently in Shanghai. Portman’s deal with Dior marks the first time the actress represents a fragrance and cosmetics brand. Exactly which new project she will be involved with still remains under wraps.
