Lady Gaga has undergone hip surgery after a concert injury left her immobile last month and forced her to cancel the remainder of her "Born This Way Ball" tour.

In a note posted late Wednesday on her Little Monsters blog, the singer, whose real name is Stefani Germanotta, thanked fans and said that they had given her "a lot of strength" during her surgery.
