Amy Winehouse Back in the Hospital

These days the words "Amy Winehouse" and "hospitalized" just seem to go together: the troubled singer was taken to the hospitalafter reacting badly to a medication on Sunday, a spokesman says.

"Some part of her medication is making her sick," spokesman Chris Goodman told the BBC. The medication formed "part of her ongoing treatment," he added.

The Grammy winner is being held for tests once again – she was also admitted in July after a similar episode with medications and collapsed in June, which revealed she has emphysema. Amy's had a rough time lately, appearing bedraggled and out of sorts when she does appear in public, and canceling multiple performances this year for health reasons.

Husband Blake Fielder-Civil, who has also been battling drug addictions, was released from jail last month on parole and has been in a rehab center ever since. Rumors that the couple are on the verge of a split have been swirling ever since another woman was seen blowing kisses to Blake during his trial for trying to cover up an attack on a pub landlord.
