Lady Gaga has torn soft tissues in her hip joint and the injury has forced her to cancel the rest of her Born This Way Ball tour to have surgery and recover, Live Nation Global Touring announced Wednesday.

Tests showed that the pop diva had torn a ring of soft elastic tissue, called the labrum, in her right hip that will require surgery to repair. The labrum follows the outside rim of the hip joint’s socket, holding the ball at the top of the femur in place. Athletes and dancers sometimes develop a tear in the tissue, and such injuries can be fixed using arthroscopic surgical techniques.

About a dozen concerts have been called off, among them a Feb. 22 show at Madison Square Garden and a March 6 show at Barclays Center in Brooklyn. Refunds for the canceled performances will be available at point of purchase starting on Thursday.

Lady Gagas' last tweet on her account was "
It will hopefully heal as soon as possible, I hate this. I hate this so much. I love you and Im sorry". We wish Lady Gaga a speedy recovery!
