Amy Winehouse might be suffering from tuberculosis as she's reportedly been coughing up blood and suffering a severe chest infection, it has emerged.
The 24-year-old has suffered further weight loss and a loss of appetite - all symptoms of the deadly disease.
Winehouse also has an irregular heartbeat and doctors have put her on a drip as they try to get her off her drug addiction
"Amy is in a bad way. Doctors are still struggling to control her heartbeat but the chest condition has been really worrying them," The Sun quoted a friend, as saying.
"She'd been been suffering horrible coughing fits and hurling up blood for a while but refused to be examined. Doctors now believe it is tuberculosis and are doing more tests to be certain," the friend added.
The 'Rehab' singer collapsed at her home in Camden, North London, on June 16 and was rushed to a clinic by dad Mitch.
Doctors were trying to discover if the collapse is related to a seizure she suffered last August when she was hospitalised after a huge drug binge.
"Things sound really bad, but at least now they have found something specific it will be easier to keep her in hospital and free from drugs," a source said.
"The word tuberculosis might frighten her into getting herself well. It certainly should do.
"She needs to realise she will die if she she doesn't clean up her act," the source added.
