The 'Material Girl' songstress had been in the intensive care unit.
There's an update on Madonna's health. ET has learned that the singer has been discharged from the hospital and is now back home feeling better.
Madonna is home resting and taking it easy per the doctor's orders. She is feeling better.
The news comes just one day after the "Material Girl" singer's manager, Guy Oseary, took to Instagram and shared she had been in the intensive care unit dealing with a serious bacterial infection. Oseary said that Madonna, 64, developed the infection on Saturday, which led to a several-day stay in the ICU.
He also went on to say that "her health is improving" and she's expected to make a full recovery. Amid the scary ordeal, Madonna has pushed the start of her Celebration Tour until further notice.
"We will share more details with you soon as we have them," Oseary added, "including a new start date for the tour and for rescheduled shows."
ET spoke to Dr. Justin Fiala, a pulmonary, critical care and sleep specialist at Northwestern Medicine, and he talked about how bacterial infections can become serious.
"It's often commonly thought that they are benign but if left untreated they can actually become quite severe and they are a common reason why people end up in the ICU," Fiala said. "Bacterial infections can even start out relatively benign in theory such as a cut on the skin that looks like a kind of localized infection but if left to just smolder and get worse they can then go to deeper sites into the body and spread and once it spreads that's usually when we're getting patients admitted to the intensive care unit."
As for when Madonna can potentially go back on tour, Fiala said it would be at least a few weeks.
"In order to get back to health, optimally the idea is that you really do want to make sure that that infection is completely treated and resolved ... the best evidence suggests that people should be taking it easier," he said. "Going straight from critical illness into something like a world tour like Madonna would be intending to do would be a really heavy lift. So what I would say is she's probably got at least several weeks in front of her of kind of targeted healing and rehabilitation to regain that stamina."
Prior to her health issues, the singer was gearing up to start The Celebration Tour, which is being put on by Live Nation. The tour was originally scheduled to begin in Vancouver, British Columbia, on July 15. Four days before her hospitalization, the GRAMMY winner had shared with fans a little behind-the-scenes of the tour's preparations.
"The calm before the storm," Madonna captioned a June 20 post.
Griffin admitted she didn't "know what's going on" with the "Like a Prayer" artist, but, nevertheless, slammed the hateful comments of "ageism and misogyny."
"Sorry, but as a 62-year-old chick I deal with it all the time, and she’s freaking Madonna," Griffin said.
She added, "I care about her health, and I’m glad she can go back on this tour. The tour is the greatest hits, and she should be great."
