Amy Winehouse is being watched around the clock by friends who are growingly increasingly concerned about the singer's health, it's been reported.

“No one wants to leave Amy on her own — she’s in a very fragile state at the moment,” a source told the Sun newspaper.

Fears about Winehouse's health intensified last week when the singer's made an impromptu appearance in London alongside her 12-year-old god daughter, Dionne.

The unnamed source said her friends are “terrified she is going to do something which she can't overcome.

“She’s been to hell and back already but some fear she’s going to get worse before she gets better,” they added.

Speaking to the Daily Mirror newspaper on Saturday, Winehouse admitted that her life was a “mess”.

“Look what happened to my dreams. This isn’t a life – I’m a mess, look at me,” she was quoted as saying.
