Amy Winehouse has been put under 24-hour surveillance by her minders, it's been reported.

Associates of the singer are said to be concerned that she has been spotted on late nights out in London just days after she was discharged from hospital.

Speaking to the Mirror newspaper, and unnamed source said: "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 - or fans - coming into her place, wreaking havoc.”

The paper claims that Winehouse has been asked to give names of people who are expected to visit the house to prevent “drug dealers coming anywhere near her.”

Winehouse was diagnosed with traces of the lung disease emphysema during a recent stay in the London Clinic in Marylebone.

The singer was admitted to the treatment centre after she fainted at her home in North London.

She was only granted temporary release last weekend in order to perform at the Nelson Mandela concert in London and the Glastonbury Festival.
