Following Amy Winehouse’s failed attempts at getting sober, the singer’s management have reportedly put her under 24-hour surveillance to stop any dealers and drug-taking pals from getting near her.

The Back To Black hitmaker was discharged from a London clinic on Monday after collapsing at her home earlier last month. She was subsequently diagnosed with traces of potentially deadly lung disease emphysema.

And, in a desperate attempt to keep her clean of drugs, executives at her music label Island Records have allegedly put her under the watchful eye of a full-time security guard.

A source says: "Effectively, Amy's been put under house arrest. She is being monitored by 24/7 surveillance to make sure she's behaving herself and keeping out of harm's way.

"There is also a security guard stationed outside her house around the clock to vet any undesirables. From now on, there'll be no more waifs and strays (random people) coming into her place, wreaking havoc.

"Crucially, they don't want known drug dealers coming anywhere near her. Amy has to give them names of people expected. Anyone who turns up uninvited will be sent packing. It's for her own good."
