Lady Gaga attends a press conference for Gaga: Five Foot Two on day 2 of the Toronto International Film Festival at the TIFF Bell Lightbox on Sept. 8, 2017 in Toronto.

She detailed her condition in a series of social-media posts, including an Instagram photo of a needle in her arm.

Lady Gaga has been hospitalized and forced to pull out of the upcoming Rock in Rio music festival in Brazil, citing "severe physical pain" and posting a photo of what resembles an IV in her arm.

The 31-year-old singer-songwriter wrote on Twitter that she had to take care of her body and asked fans for their "grace and understanding."

Her representatives said in a statement that Lady Gaga was suffering from "severe physical pain" that affected her ability to perform and that she was under the care of "expert medical professionals."

It wasn't clear what she was suffering from or where she was being treated. She posted a photo on Instagram of her arm with a needle in it and a tube running outside the photo's frame.
