Lady Gaga will have surgery to repair a tear in her hip, which forced the cancellation of the rest of her Born This Way Bill, tour, according to CNN.

The singer whose real name is Stefani Germanotta, has a labral tear of the right hip caused by strenuous repetitive movements, the tour operator said. "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," a statement said.

After initially postponing several concert dates, Lady Gaga was forced to cancel the remainder of her Born This Way Ball Tour, concert promoter Live Nation Global Touring announced on its website on Wednesday Feb. 13. With 21 remaining concert dates through March 20 on the schedule, fans can get refunds for the cancelled performances at the point of purchase starting Thursday.

News reports described the Bad Face singer's injury as synovitis, a severe inflammation of joints.

She posted this Facebook message on Tuesday, saying,

"There's an unfortunate announcement coming out right now, concerning myself and the Born This Way Ball. Im so sorry. I barely know what to say. 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. I hid it from my staff, I didn't want to disappoint my amazing fans. However after last nights performance I could not walk and still can't."

The worldwide Born This Way Ball tour grossed over $161 million last year, making it the fifth-highest grossing tour of 2012, according to US Weekly.

Gaga also followed up with a Facebook announcement to her fans on how they can refund concert tickets.

Her next album, ARTPOP, is scheduled for a September 2013 release date.

"The album is going to be an app. It will also exist in CD and digital form, but the primary experience will be as an application. It will be built around the tablet, but will have a mobile version as well," Gaga's manager Troy Carter said in an interview with V Magazine.
