Amy Winehouse is still in the hospital after fainting in her London home yesterday.

Today, tests showed the results were inconclusive.

Inconclusive????

Please, it doesn't take a doctor to analyze her blood: crack, heroin, cocaine, ecstasy and cat urine.

Winehouse was supposed to be released today, though doctors want to keep her in for some extra tests.

A rep for Amy says, "She's staying there for the time being. They are still not quite sure what happened and the tests were inconclusive. Doctors want to get to the bottom of it before releasing her. There will be further tests and they will keep her under observation. She seems to be fine … but they are taking their time to be sure."

Amy's dad, Mitch, has been talking to the press a bit, even admitting that his daughter's visit to rehab back in January for two weeks was a failure.

He adds, "She didn't want to get clean then, but she's talking about it now. She's nowhere near as bad as she was. A nurse visits twice a day and we're kept well informed about how she's doing. She's making progress."

Translation: She's still using drugs. What can we do????

And as for Amy and Blake, their relationship, and any future kids, Poppa Wino adds, "Amy understands Blake might have to do a long time in prison – she's not stupid. But she'll stand by him and he'll stand by her. She wants kids and knows she can't be taking drugs, or the baby would be addicted – she wouldn't do that."

Please. Someone get this girl on birth control.

We don't need to see little Amy's running around!
