Amy Winehouse Hospitalized (Again), Released

Troubled singer Amy Winehouse was released from a London hospital Tuesday after an overnight stay to treat "an adverse reaction to medication."

That's what they're caling it now, apparently.

Amy Winehouse was discharged from London's University College after spending the night in observation, said spokesman Chris Goodman.

The singer was rushed to the hospital's emergency room by ambulance from her north London home Monday night. Goodman said the medication she had been taking was ingested her home, but did not provide further details.

"She had a bit of a scare yesterday because of a reaction to treatment. She was kept in overnight purely for observation," Goodman said. "Amy is at home now after leaving with her father and manager. She is having a rest."

Amy Winehouse, who won Grammys and acclaim for her 2006 album Back to Black, was admitted to a London clinic in June after collapsing at home.

Her father, Mitch Winehouse, said at the time she had developed early stage emphysema from smoking cigarettes and crack cocaine.

The singer was released to perform at celebrations for former South African president Nelson Mandela's 90th birthday in London's Hyde Park.

In addition to her myriad health woes, Amy Winehouse has had several run-ins with police in recent months.

She was investigated by police after a tabloid newspaper published a video that appeared to show her smoking crack cocaine. She was not charged.

Police also cautioned Winehouse in April for assault after she slapped a man during a night out. Once again, she was arrested but not charged.

Her husband, Blake Fielder-Civil, was sentenced to 27 months in jail for assault and obstructing justice. He's already been in there for nine.
