Gaga needs surgery on a hip injury, with doctors ordering her to rest...
Lady Gaga has had to cancel the remaining dates of her Born This Way Ball tour after it emerged that she needs surgery.
As we reported yesterday (February 13), the Poker Face star was forced to scrap two concerts in Chicago, as well as shows in Detroit and Hamilton after suffering from synovitis - inflammation of the joints.
Despite Gaga hoping that her injury would "heal as soon as possible", it has now been confirmed that she needs an operation on her hip, with doctors ordering her to rest after the procedure.
A statement posted on her social-networking site Little Monsters said: "Live Nation Global Touring has confirmed that the remainder of the Lady GaGa 'Born This Way Ball' performances have been cancelled.
"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 down time to recover. This unfortunately, will force her to cancel the tour, so she can heal."
It concluded: "Refunds for the cancelled performances will be available at point of purchase starting Feb 14, 2013."
