Madonna, 64, pictured for the first time since announcing rescheduled tour dates - as she recovers from health battle

Madonna has been pictured out for the first time since announcing she will be rescheduling her world tour dates, after suffering a serious health battle stemming from a bacterial infection.

The 64-year-old Ray of Light star was seen on Saturday in New York City wearing a pair of her own $45 'Madame X Spectral Shorts' and a baseball cap with the slogan 'spiritually hungry.' 

Her outing comes as the star recently told fans that she would be re-scheduling dates from her 84-date Celebration world tour after delaying the show due to her recent hospitalization. 

'Thank you again for your incredible support and patience over these past few weeks!' she announced last week. 'I'm happy to report that the re-routed tour schedule will be coming in the next few days!'

In July, pop icon revealed that she was on the road to recovery and said she planned to reschedule her Celebration Tour for later this year.

She shared a glamorous new photo of herself at her NYC home as she thanked fans for their well-wishes.

Madonna wrote: 'Thank you for your positive energy. Prayers and words of healing and encouragement. I have felt your love.

'I'm on the road to recovery and incredibly grateful for all the blessings.

'My first thought when I woke up in the hospital was my children. My second thought was that I did not want to disappoint anyone who bought tickets for my tour.

'I also didn't want to let down the people who worked tirelessly with me over the last few months to create my show. I hate to disappoint anyone.

'My focus now is my health and getting stronger and I assure you I'll be back with you as soon as I can

'My current plan is to reschedule the North American leg of the tour and to begin in October in Europe.

'I couldn't be more grateful for your care and support. Love, M.'

Madonna was given an injection of the drug Narcan - commonly used to reverse suspected drug overdoses - to combat acute septic shock before she was rushed on to hospital, reported Radar Online.

The singer has been mostly bedridden as she remains 'weak and very tired' following the ordeal.

Sepsis is a life-threatening condition caused when the body releases chemicals to fight an infection.

These chemicals damage the body's own tissues and organs and can lead to shock, organ failure and death.

Organ failure and death are more likely if sepsis is not recognized early and treated immediately.

DailyMail.com contacted representatives for the star for comment.

The Vogue singer's health crisis came ahead of her postponement of The Celebration Tour, an 84-date trek which was slated to kick off July 15 in Vancouver at the Rogers Arena.

Last month, Madonna's manager Guy Oseary said that 'at this time we will need to pause all commitments, which includes the tour.'

Madonna had dealt with a fever for a month, insiders told the outlet, but kept things under wraps in hopes of keeping her tour intact.
