Amy Winehouse is suffering from food poisoning.
The 27-year-old singer - who is currently recording the follow-up to her highly acclaimed 2006 album 'Back to Black' - has checked herself into a Harley Street clinic in London because she is feeling so ill as a result of eating something unsavoury, telling other patients she is feeling "dog rough".
A source told The Sun newspaper: "Amy is in the clinic being treated for food poisoning.
"She hasn't said what she's eaten but has been telling patients that she feels dog rough."
Amy's sickness comes at a time when the singer - who has a history of drug addiction - is said to be trying to get healthier than ever as she is hoping to have a child with boyfriend Reg Traviss.
A source said recently: "Amy's obsessed with having children. It's all she's talking about right now. She is desperate to have a baby within the next year.
"Amy is doing everything she can to have kids. Because of the drugs and drinking, her body would not have been able to handle a baby. Now she's on the road to recovery and is turning things around."
