Amy Winehouse is experiencing a major set back after her third studio album is scheduled to be delayed and her appearance in U.S. has been axed. The British import, also famous for her erratic behavior, has been singled out of a charity event in New York on May 5 with a reason from the organizers that they have "moved on from her".

Organizers of Metropolitan Museum of Art's annual Costume Institute gala said that she is no longer part of the show even though she's been granted a business visa to enter the States following a denial earlier this year. A spokesman for the gala told Daily Mail, "She was asked if she would be interested, and she was considered, but then we moved on from her."

A source close to Winehouse said that the singer was actually "looking forward to going to America" and that this cancellation "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."

Last week, it was also reported that her third album was going through a stalling also. The singer pulled out of a planned trip to Bahamas to record the album and her label now predicts that the CD will only come out in 2009 instead of later this year.
