The health condition of the Pop music diva is serious and the family members are preparing for the worst, writes the Daily Mail.
The 64-year-old was found unconscious in New York on Saturday and taken to hospital, where doctors say she was intubated overnight.
Meanwhile, yesterday her manager Guy Oseary said that the POP world star was affected by a serious bacterial infection for which she had to undergo treatment in the hospital and therefore had to postpone her tour in Vancouver.
A relative of the Michigan-born singer told DailyMail.com that they were going through a difficult time and were unsure if she would make it.
Her family was preparing for the worst. Everyone believed they could lose it. That is why it was initially kept a secret," said the relative.
Madonna is the mother of six children: Lourdes, 26; Rocco, 22 years old; David, 17; Mercy, 17 years old; and 10-year-old twins Stella and Estere.
