Winehouse Back in Hospital

After a bad reaction to her medication, a spokesman said troubled soul singer Amy Winehouse is back in the hospital, according to the Associated Press.

The singer is currently being treated at the private London Clinic, where she was admitted Sunday. Winehouse's spokesman, Chris Goodman, declined to state to what medication Winehouse was reacting.

Winehouse has been hospitalized several times this year, most recently for a chest infection. The 25-year-old also has a history of drug problems, though it is unclear if drugs are a factor in the recent hospitalization. In January, Winehouse spent two weeks in a drug rehab clinic.

On Monday, Winehouse's husband, Blake Fielder-Civil, was declined an appeal against his 27-month sentence for obstruction of justice and assault. Fielder-Civil was transferred to a drug rehabilitation center earlier this month, where he continues to seek treatment.

The 25-year-old singer won several Grammy awards earlier this year for her hit single, "Rehab." She was also nominated for her album, Back to Black, which won "Album of the Year" at the MTV Europe Music Awards in 2007.
