A day after postponing her Chicago concerts, Lady Gaga has canceled them for good, along with the rest of her tour.
Tour promoter Live Nation said Wednesday that a tear in her right hip will require surgery followed by a recovery period.
Refunds are available at the point of purchase.
The pop star had 21 dates through March 20 remaining on her "Born This Way Ball" tour schedule. She postponed four dates on Tuesday, including two this week at the United Center, after telling fans in a tweet she'd hurt herself some time ago, but hid the injury from her staff.
Over the last month, the injury became worse and she said she was unable to walk following a performance Monday in Montreal.
