R&B singer Amy Winehouse has been temporarily released from rehab to apply for a U.S. visa. Accompanied by her father Mitch and a clinic nurse, the 24-year-old British star left the London clinic for a few hours to meet with U.S. Embassy officials in her latest bid to attend the Grammy Awards in Los Angeles on February 10. But a spokesperson for the Back to Black star said no decision had been made on whether or not she will attend the ceremony. A statement reads: “The appointment at the US Embassy was made some time ago and was part of process for obtaining a visa. No decision has been made about the Grammys. “Amy was accompanied by a nurse as the appointment was under supervision. She has not left rehab and remains under the care of the clinic.” Winehouse was banned from the U.S. last October after she was arrested and fined in Norway for possession of cannabis.
