Lady Gaga says she broke her hip months ago

NEW YORK, July 29 (UPI) -- U.S. pop star Lady Gaga has revealed a broken hip prompted her surgery and concert tour cancellation earlier this year.

"I had broken my hip. Nobody knew, and I haven't even told the fans yet," the 27-year-old singer told Women's Wear Daily.

"But when we got all the MRIs finished before I went to surgery there were giant craters, a hole in my hip the size of a quarter, and the cartilage was just hanging out the other side of my hip," Lady Gaga said. "I had a tear on the inside of my joint and a huge breakage. The surgeon told me that if I had done another show I might have needed a full hip replacement. I would have been out at least a year, maybe longer."

The recording artist is scheduled to return to the stage and perform her latest, as-yet-untitled single at the MTV Video Music Awards Aug. 25 in New York.
