Concerns are mounting that Grammy winner Amy Winehouse has tuberculosis. The “Rehab” star has been under observation in a London hospital since passing out in Camden apartment on Monday. According to a new tabloid report, Amy has been coughing up blood and suffering with a painful chest infection since she was admitted to the hospital, prompting doctors’ fears that the twenty-four year old singer could have a violent strain of TB.

“Amy is in a bad way. Doctors are still struggling to control her heartbeat but the chest condition has been really worrying them,” a spy tells The Sun. “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.”
