It wasn’t just tour rehearsals which had Madonna feeling exhausted ahead of her collapse last weekend.
The Sun reports that just hours before being found unresponsive in her New York home, the Like A Prayer singer was locked in the studio with fellow pop superstar Katy Perry.
Madge is reported to have felt under the weather in the run-up to her shock blackout but she was determined to push on with her gruelling schedule.
This included punishing 12-hour days rehearsing at Nassau Coliseum in Long Island ahead of her 84-date Celebration Tour, which has now been postponed.
The superstar had also been working with Perry on a special project as part of her celebrations to mark her 40 years in the business.
A source said: “Madonna has long admired Katy and they have worked together before but never managed to actually put anything out.
“Madonna has been working around the clock to make sure both her music and her world tour are second to none.
“Obviously everything has been put on hold now but the fact she was in the studio with Katy just hours before being rushed to the ICU shows how determined she was to push ahead despite feeling unwell.”
On the same day, Madonna was also spotted visiting New York’s Metropolitan Museum of Art, which is the location for the world-famous A-lister black-tie fundraiser, the Met Gala.
The music icon is said to have been suffering with illness for a month but refused to cut down her schedule as she was determined to make sure everything was perfect.
Madonna’s Celebration Tour was due to kick off in Vancouver, Canada in a fortnight’s time.
The trek included five sold-out nights at London’s O2 Arena in October and December.
However, earlier this week her manager confirmed all work commitments are now on ice while Madonna recovers.
The Material Girl was raced to the hospital last Saturday after developing a serious bacterial infection.
Her manager Guy Oseary, who has worked with the superstar for decades, said: “Her health is improving, however she is still under medical care. A full recovery is expected.”
She is now understood to have been discharged and is back at her New York home but is under the watchful eyes of doctors.
