Amy Winehouse hospitalized for chest infection

The Daily News is reporting that Amy Winehouse has been in the hospital since fainting Monday because she has tuberculosis. They’re also saying Amy’s massive weight loss has hindered her recovery – and that she won’t let doctors treat her.

As Amy Winehouse remains in the hospital, it's being reported that the 24-year-old has a case of tuberculosis.

With a chest infection and the songstress coughing up blood, sources inside the London hospital report her doctors are trying to control her irregular heartbeat.

"She'd 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 source told London's The Sun newspaper.

Winehouse's massive weight loss since she sky-rocketed to fame in 2004 is also a concern of doctors.

However Amy’s rep officially denied the TB report, stating that Amy has some sort of chest infection, and doing his best to make it sounds like it’s relatively mild.

Amy Winehouse has been tested for tuberculosis during her prolonged hospital stay, her rep tells PEOPLE. "She has a chest infection and she had a routine test for TB, which came back negative," Chris Goodman tells PEOPLE.

Goodman also denies a report – in U.K. tabloid The Sun – that she has been coughing up blood at the London clinic where she was taken after fainting earlier this week.

The troubled singer, 24, is still undergoing tests and doctors will soon decide whether she is able to keep her upcoming performing commitments. One insider says her chances of performing for Nelson Mandela's 90th birthday celebration in London on June 27 are "50/50."

"She would really love to do the show – she always wants to do these things," said Goodman. "But she will listen to her doctors."

Amy Winehouse not showing up to a big performance isn’t exactly newsworthy anymore. Having a legitimate excuse NOT TO be there is definitely newsworthy, at least for her. I think it’d be great if doctors keep her in the hospital as long as possible. It certainly couldn’t make things worse. Though one has to wonder if she’s also going through withdrawals, since presumably she’s not shooting up in the ICU. Though if anybody could figure out a way to get it done, it’s Winehouse.
