Lady Gaga has torn soft tissues in her hip joint and the injury has forced her to cancel the rest of her "Born This Way Ball" tour to have surgery and recover, Live Nation Global Touring announced Wednesday.
"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," it added.
The tour kicked off on Jan. 14 in Tacoma, Wash., and the massive two-year tour was meant to span six continents.
The cancellation of the 21 dates is estimated to cost the industry more than $35 million in lost revenue, according to the Chicago Tribune. She earned $161 million on the road last year.
Refunds for the canceled performances will be available at point of purchase starting on Thursday.
