The remaining dates of Lady Gaga's Born This Way Ball have been cancelled, Live Nation confirmed on Wednesday.

"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 caused by strenuous repetitive movements in her performances," a statement on her Little Monsters site explained. "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."

On Tuesday, Gaga revealed she'd been injured and announced she was postponing several dates.

"I've been hiding a show injury and chronic pain for sometime now,over the past month it has worsened. I've been praying it would heal," she tweeted, adding, "After last night's performance I could not walk."

She has yet to address today's news on her Twitter page, though she apologized profusely to fans on Tuesday.
