AMY WINEHOUSE was released from a London jail Saturday morning, the Associated Press reports. The Grammy winning singer was cautioned by police for common assault, stemming from an incident earlier this week where she allegedly headbutted a fellow bar patron.
The "Rehab" singer was taken into custody Friday afternoon but a doctor decided she was "in no fit state" to be questioned so she was kept in a cell overnight until a doctor gave the go-ahead for her to be interviewed Saturday morning.
