Lady Gaga postpones European leg of world tour

London - Lady Gaga has postponed her world tour's European leg until next year because of ongoing health problems.

The six-week part of the Joanne World Tour was set to kick off in Barcelona on 21 September.

Tour promoter Live Nation says that "Lady Gaga is suffering from severe physical pain that has impacted her ability to perform. She remains under the care of expert medical professionals who recommended the postponement."

Last week, the 31-year-old singer-songwriter pulled out of a performance in Brazil after being hospitalised with "severe physical pain." Earlier this month, Lady Gaga postponed a Montreal concert.

Lady Gaga said on Monday on Instagram that's she been honest about her "physical and mental health struggles" and has been "searching for years to get to the bottom of them".

I have always been honest about my physical and mental health struggles. Searching for years to get to the bottom of them. 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. 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. 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.
