Winehouse will not be attending the NJR Music Awards in Cannes, where she was to perform. The singer has been re-admitted to a rehabilitation centre.
"Amy decided to enter the facility today after talks with her record label, management, family and doctors," reads a statement from the Universal Music Group. "She has come to understand that she requires specialist treatment to continue her ongoing recovery from drug addiction and prepare for her planned appearance at the Grammy Awards."
The popular singer is not expected to attend the Grammy Awards on February 10. Winehouse has been nominated for six Grammys.
