Amy Winehouse will not be singing at the prestigious Costume Institute Gala in New York this May, according to sources. The troubled singer was hoping to break America with a performance at the star-studded bash and had even been granted a business visa allowing her to work in the US. But a source revealed, “She has been told that she is no longer part of the program. She was really looking forward to going to America… But now the trip is off. It seems Amy has slipped into her old ways and even her record label were concerned she wasn’t up to the trip. It will be a huge blow for her as it would have been a great platform to break America. They love her music over there, but Amy has yet to do a tour.” An insider for the event confirmed the decision, saying, “She was asked if she would be interested, and she was considered, but then we moved on from her.”
