'Black Swan' star Natalie Portman wears a simple monochrome dress as she arrives at the Ed Sullivan Theater in New York for 'The Late Show With David Letterman'. She waves at fans and briefly stops to pose for photos before going inside. She doesn't stop on leaving the studio but simply rushes to her awaiting car.
The actress stars in the newly released 'Thor: The Dark World' as Jane Foster, Thor's mortal lover. She is also set to star alongside Ewan McGregor in the upcoming Western 'Jane Got a Gun'.
