Amy Winehouse won't be performing at this year's Grammy Awards because her request for a visa was turned down by the U.S. Embassy, her publicist said Thursday.

"Amy has been progressing well since entering a rehabilitation clinic two weeks ago and although disappointed with the decision has accepted the ruling and will be concentrating on her recovery," the Outside Organization, which counts the troubled retro-soul sensation among its clients, said in an e-mail.

The statement didn't say why her application had been rejected but it might just have something to do with all those "incidents" she's had lately.
