Pop icon Madonna was hospitalized and required a stay in the intensive care unit (ICU) after developing a "serious" infection, according to her team.
The 64-year-old "Like a Virgin" singer was rushed to the hospital on Saturday, according to Guy Oseary, Madonna's longtime talent manager. He also revealed dates on her Celebration World Tour would be rescheduled.
"On Saturday June 24, Madonna developed a serious bacterial infection which lead (sic) to a several day stay in the ICU," Oseary wrote Wednesday on Instagram.
"Her health is improving, however she is still under medical care. A full recovery is expected."
Madonna previously canceled a string of shows on her last tour in 2019, due to a knee injury, and ultimately ended the tour early.

"We will share more details with you soon as we have them, including a new start date for the tour and for rescheduled shows," Oseary added.
Fox News Digital has reached out to Madonna's representatives for comment.
Fox News medical contributor Dr. Marc Siegel said a number of different issues could cause concern and prompt immediate attention.
"Most commonly, I would be concerned about the possibility of pneumonia or a urinary infection that spread to the blood and the lungs," he told Fox News Digital.
"A stay in the ICU is very serious, and it shows that someone was in a life-threatening situation. If they get out of the ICU, it’s very optimistic that they’re then going to recover."
The "Vogue" singer planned to launch her Celebration World Tour in July, which also marked her 40-year anniversary in the entertainment industry.

Fans have previously dealt with concert woes from the Queen of Pop after she canceled shows on her Madame X Tour in 2019.
In February, Madge mourned the loss of her older brother, Anthony Ciccone.
The "Like a Prayer" singer broke her silence on Anthony's death with a throwback snap and a list of a few pivotal points she learned from her late sibling.
"Thank you for blowing my mind as a young girl and introducing me to Charlie Parker, Miles Davis, Buddhism, Taoism," Madonna wrote underneath a photo with her brother.
She added a few more notable teachings: "Charles Bukowski, Richard Brautigan, Jack Kerouac, Expansive Thinking Outside the Box."
"You planted many important seeds," she wrote.
Madonna was one of seven children and has two half-siblings from her father's second marriage. Anthony reportedly struggled with alcoholism and became estranged from his family. He spent many years homeless, but reportedly reconnected with family members in 2017 after entering rehab.
