Fortunately tuberculosis tests have proved negative for the singer who has been in hospital since she collapsed on Monday.
Doctors suspected she had TB and banned family and friends from visiting. But they are still not sure what is wrong with her.

Only her dad Mitch has been allowed to see her.
A source told The Sun: "Doctors have to take this very seriously.
"She is coughing and spluttering all over the place so visitors would be at risk of catching whatever she has."
Relatives are hoping she will give up plans to perform at Glastonbury and Nelson Mandela's 90th birthday party next weekend.
"Doctors still aren't sure what is wrong with her so she must give them more time," the source said.
"Hopefully she will stay in long enough to clean herself up.
"It's approaching a week now since she's taken drugs. It's the first time we've been able to say that in ages.
"This could be her chance to get herself off this stuff which is killing her. If she goes back on stage she will probably get back into bad habits."
