This was bound to happen!

Amy Winehouse's friends are so worried about her, they are begging she go back to rehab.

The Sun is reporting that Wino's friends are witnessing her slowly returning back to her old ways ever since she left a rehab clinic a few weeks ago.

We've said it before. We'll say it again.

You can't treat a crack and heroin addiction in TWO WEEKS!

Even her incarcerated hubby, Blake Fielder-Civil, has threatened to ban Ames from visiting him in jail because he's convinced she's still on crack cocaine.

You know his motto. If he can't have any, neither can she!

A friend of Winehouse's says, "Amy’s in an awful state again. She’s clearly on drugs. Many of us think full-time residential rehab is the only option but she won’t go back."

Amy has recently been spotted with scratches on her arms and mysterious marks and spots on her knuckles. Wino has a troubling history of self-harming while being high on drugs.

A source also added that Winehouse "was smoking cannabis and drinking heavily as soon as she left rehab. That has now increased. Everyone who’s seen her in the last week or so has been really disturbed by the state she’s in. She’s getting back to her worst. It was hoped her new album and fashion range would keep her focused but it hasn’t worked."

Get her back to rehab! NOW.
