Kristen Stewart’s Quick Change in NYC (PHOTOS)

Kristen Stewart needed a little assistance in avoiding the paparazzi outside Nobu in New York City on Monday evening.

The Welcome to the Rileys star, who’s in town to promote her new film, was first spotted leaving the screening party for her film in her adorable premiere dress. Later, Kristen changed into a cute green beanie and sunglasses. While KStew has a reputation for looking a little sullen in photos, she was all smiles when she greeted a mob of adoring fans.
