Lady Gaga Cancels Remaining 'Born This Way Ball' World Tour Dates To Have Hip Surgery

The 'You & I' singer has offered refunds for the final 21 dates of her world tour and will undergo surgery to repair her hip.

Lady Gaga has been forced to cancel all remaining dates on her 'Born This Way Ball' world tour to undergo surgery on a tear in her right hip, it has been announced.

In a statement released on Wednesday (13th February), the show's promoters Live Nation confirmed the final 21 dates on the world tour had been cancelled, following news earlier this week that the 'Marry The Night' star was suffering from synovitis and had been left temporarily unable to walk.

Gaga originally postponed just four tour shows this week after revealing she had been hiding her injury and "chronic pain" from both staff and fans alike, posting that she was "devastated" to be letting her fans down.

"Live Nation Global Touring has confirmed that the remainder of the Lady Gaga Born This Way Ball performances have been cancelled," the promoter announced in a statement. "After additional tests this morning to review the severity of the issue, it has been determined that Lady Gaga has a labral tear of the right hip.

"She will need surgery to repair the problem, followed by strict down time to recover," the statement reads. "This unfortunately, will force her to cancel the tour, so she can heal.

"Refunds for the cancelled performances will be available at point of purchase starting Feb 14, 2013."

The 'You & I' star has yet to post an official comment on the tour cancelation, but earlier this week told fans: "I hate this so much. I love you and I'm sorry".

US pop star Gaga has been working hard on her new album 'ARTPOP' in recent months which is expected to see a release this autumn.

Lady Gaga's 'Born This Way Ball' world tour original launched back in April 2012 and had been scheduled to come to a close on 20th March.
