After first announcing that only a few concerts would be postponed due to injury, Lady Gaga last night canceled the remainder of her "Born This Way" tour.
In a statement to Newsday, Gaga's spokeswoman, Amanda Silverman, said that concert promoter Live Nation Global Touring "has confirmed that the remainder of the Lady Gaga Born This Way Ball performances have been canceled."
Gaga said on Tuesday that due to synovitis, a severe joint inflammation, she was forced to postpone performances set for Feb. 13-14 in Chicago, Feb. 16 in Detroit and Feb. 17 in Hamilton, Ontario, Canada.
But, the statement continued, "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 downtime to recover. This unfortunately, will force her to cancel the tour, so she can heal."
"Refunds for the canceled performances will be available at point of purchase starting today."
After the original announcement Tuesday, Gaga apologized to fans on her Twitter page. "I'm so sorry," she wrote. "I barely know what to say. I hid it from my staff. I didn't want to disappoint my amazing fans. However, after last night's performance I could not walk and still can't."
She had been scheduled to play Madison Square Garden on Feb. 22 and 23 and Barclays Center on March 6.
Gaga has been touring since last April, beginning in South Korea, and has performed more than 100 concerts in support of her 2011 album "Born This Way."
