Lady Gaga Postpones European Leg of 'Joanne' World Tour Due to Severe Physical Pain

"I have always been honest about my physical and mental health struggles," Gaga wrote on Twitter and Instagram. "It is complicated and difficult to explain, and we are trying to figure it out."

"As I get stronger and when I feel ready, I will tell my story in more depth, and plan to take this on strongly so I can not only raise awareness, but expand research for others who suffer as I do, so I can help make a difference," she continued. "I use the word 'suffer' not for pity, or attention, and have been disappointed to see people online suggest that I'm being dramatic, making this up, or playing the victim to get out of touring. If you knew me, you would know this couldn't be further from the truth."

"I'm a fighter," Gaga continued. "I use the word suffer not only because trauma and chronic pain have changed my life, but because they are keeping me from living a normal life. They are also keeping me from what I love the most in the world: performing for my fans. I am looking forward to touring again soon, but I have to be with my doctors right now so I can be strong and perform for you all for the next 60 years or more. I love you so much."

Gaga also posted a press release from Live Nation, confirming the postponment and citing "severe physical pain" as the reason for her inability to perform.

"Lady Gaga is suffering from severe physical pain that has impacted her ability to perform," Live Nation said in the statement. "She remains under the care of expert medical professionals who recommended the postponement earlier today. Lady Gaga is devastated that she has to wait to perform for her European fans."

The six-week European leg of the tour was scheduled to begin on Sept. 21 in Barcelona, Spain, and conclude on Oct. 28 in Koln, Germany.

Gaga previously canceled her Friday performance at the annual Rock in Rio music festival in Brazil on Thursday of last week, posting about her pain and devastation on Twitter.

"Brazil, I'm devastated that I'm not well enough 2 come to Rock In Rio," she tweeted. "I would do anything 4 u but I have to take care of my body right now. I ask for your grace and understanding, and promise that I will come back and perform for you soon. I was taken to the hospital its not simply hip pain or wear & tear from tour, I'm in severe pain. I'm in good hands w/ the very best doctors."

Gaga even gave a shoutout to Selena Gomez, who suffers from lupus and revealed last week she received a kidney donation from her friend Francia Raisa back in May.

"Prayers & love to @selenagomez you are a warrior princess," Gaga posted. "What an inspiration."

Gaga had been posting about her recent chronic pain since Tuesday of last week, mentioning her ongoing battle with fibromyalgia, which is a chronic disorder that causes widespread muscle pain and tenderness and can sometimes cause fatigue, memory issues and mood swings.

"In our documentary the #chronicillness #chronicpain I deal w/ is #Fibromyalgia I wish to help raise awareness & connect people who have it," Gaga shared. "Thought ice helped #Fibromyalgia. I was wrong & making it worse. Warm/Heat is better. Electric Heated Blanket, Infrared Sauna, Epsom Baths."

The "Joanne" World Tour was Gaga's fifth headlining concert tour in support of her fifth studio album, "Joanne." It began Aug. 1 of this year in Vancouver, Canada, and was scheduled to conclude in 2018 in Europe. Various shows in Europe and North America sold out quickly, which prompted the singer and her team to schedule additional dates in both continents.

UPDATE at 3:00pm on 9/20/17: A previous version of this post said Lady Gaga canceled the European leg of her tour. At this point, it has only been postponed until "early 2018."
