Lady GaGa 'Born This Way Ball' tour 'rehearsal audio' emerges - listen

Audio from Lady GaGa's rehearsal for her 'Born This Way Ball' has apparently emerged online.

The clip - recorded in Seoul, Korea - is said to be of GaGa performing album track 'Government Hooker' in preparation for her live shows.

Near the end of the clip, it has been speculated that the pop superstar says: "Welcome to the 'Born This Way Ball'," suggesting 'Government Hooker' may be the first song of the show.

Lady GaGa will play 110 dates spanning over a year for the 'Born This Way Ball' jaunt, which kicks off in South Korea this Friday (April 27).

GaGa previously released a picture of her constructing the stage for the tour.
