Madonna's Instagram account has been flagged for allegedly sharing "false information" about coronavirus.

The 61-year-old singer — who recently claimed to have battled the virus back in March — has had one of her posts marked by Instagram, after it contained information about a possible cure for the illness, which was deemed "false" by the photo sharing site.

In the post — which has now been deleted — Dr. Stella Immanuel alleged that a cure has "been found and proven and has been available for months" through the antimalarial drug hydroxychloroquine.

According to The Daily Beast, Madonna had written alongside the video: "They would rather let fear control them and let the rich get richer and the poor and sick get sicker. This woman is my hero — thank you Stella Immanuel."

Prior to the post's deletion, Instagram censored the video by blurring the clip and adding a "false information" caption, as well as including a link to an informative website that debunked Immanuel's claims.

​​​​​​​Madonna singer previously revealed she has antibodies for the respiratory condition, after contracting the virus while on her 'Madame X' tour in March.

Alongside an image of a news article explaining she has donated over US$1 million to help find a vaccine, she wrote: "I'm Grateful that I can be a part of supporting Research to Find the cure for Covid -19!!

"And just to clear things up for people who would rather believe sensationalist headlines than do their own research about the nature of this virus--

"I am not currently sick.

"When you test positive for anti-bodies it means you HAD the virus which I. clearly did as I was sick at the end of my tour in Paris over 7 weeks ago along with many other artists in my show but at the time

"We all thought we had a very bad flu. Thank God we are all healthy and well now. Hope that clears things up for the band wagon jumpers!! Knowledge is Power! #covid19 (sic)"— BANG
