Amy Winehouse, 25, has been laid up in the hospital since suffering a drug and alcohol-induced seizure last week. The Sun reports that the "Rehab" singer gave her 26-year-old hubby Blake Fielder-Civil a goodbye shag in her hospital bed—just before he was sent back to prison.

Fielder-Civil had been out on early release from a sentence for "perverting the course of justice."  He was sent back to the pokey after failing a drug test in rehab. But not before scoring a little action from a bedridden Amy on Tuesday night.

According to the paper's source, after learning of the drug-test results Fielder-Civil rushed to Amy's side at the London Clinic, where she's been recuperating.  He supposedly then persuaded Amy's caretakers to grant them an hour-long block of "private time."

Though the couple recently broke up, Blake is assumed to have told Amy how sexy she looked in her hospital bed. From there, "It was obvious what went on."

After making love, Fielder-Civil handed himself in to police in Shoreditch, East London.

Which seems perfectly reasonable. Dude has a lot to atone for. Failing his drug test is really the least of it.
