Lady Gaga will have to miss this year's "Rock In Rio" music festival after she was rushed to the hospital due to severe pain. In an Instagram post on Thursday, the singer-songwriter uploaded a photo of her Rio tattoo and delivered the sad news to her millions of followers.

"It is not simply hip pain or wear and tear from the road, I am in severe pain," she wrote. "But am in good hands with the very best doctors. Please don't forget my love for you."

Singer sends message to fans after last-minute cancellation

She reassured her fans that Rio will always have a place in her heart despite having to withdraw her performance on Friday.

The heartfelt message was a follow-up to another post that confirmed her absence from "Rock in Rio" music festival. The 31-year-old artist also apologized to her fans and asked for their understanding over the decision.

"I ask for your grace and understanding and promise that I will come back and perform for you soon. I'm so sorry, and I love you so much," she said.

Her representatives also released an official statement to explain the last-minute decision. It said that Lady Gaga suffered from severe physical pain that has affected her ability to perform for the "Rock in Rio" music festival.

A few days before she was hospitalized, the "Bad Romance" artist took to social media to share that she is suffering from a chronic illness called Fibromyalgia or Fibromyalgia Syndrome (FMS) that causes body pain.

Lady Gaga is hoping that opening up about her health condition will raise the awareness of people on the disorder.

She is expected to talk further about the chronic illness in "Gaga: Five Foot Two" documentary which is slated to be released this September 22 on Netflix.

Lady Gaga's health condition prevents her from performing

This is not the first time Lady Gaga has canceled a show due to a health condition. In 2013, the singer-songwriter had to cancel the remainder of her "Born This Way Ball" concert tour due to hip pain.

Similarly, the Mother Monster canceled her Montreal performance earlier this month after she fell ill. The devastated singer penned a lengthy letter to her fans to apologize for the sudden changes in her concert tour schedule before she announced that she was sending over free pizza to fans waiting outside her hotel in Canada.

Lady Gaga's "Joanne World Tour" kicked off on August 1 and will run until December 18. She is set to hold a two-day show in Spain on September 21 and 22 to open the European leg of the concert tour.
