Lady Gaga Cancels Born This Way Ball Tour Due to Severe Injury
02/13/2013 AT 08:50 PM EST
Following Tuesday's Facebook announcement that she was "devastated and sad" because she couldn't walk and had to postpone several Born This Way Ball concerts, the pop star, 26, has officially canceled the remaining dates of her world tour.
"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," the singer's rep told PEOPLE Wednesday in a statement. "She will need surgery to repair the problem, followed by strict down time to recover. 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 on Thursday.
"I hope you can forgive me, as it is nearly impossible for me to forgive myself," she wrote the previous day of postponing the dates. "I hate this. I hate this so much. I love you and I'm sorry."
Get well, Gaga!
