LONDON (AP) -- A spokesman for troubled singer Amy Winehouse says she has been released from a London hospital after suffering a reaction to medication.

Spokesman Chris Goodman says Winehouse is feeling fine. He says she was discharged from a London hospital Tuesday after spending the night under observation.

Winehouse had been rushed by ambulance from her north London home to London's University College Hospital on Monday evening.

It was the second time in as many months that the Grammy winner had been taken to a hospital. She was hospitalized in June after collapsing at home.
