On June 12 2012, Lady Gaga hit back at Madonna after the Queen of Pop made a public dig at her by performing a mash-up of her own Express Yourself and Gaga’s Born This Way during her MDNA World Tour.

Gaga was clearly unimpressed by the stunt and decided to retaliate during a concert in Auckland, New Zealand, telling fans: “You could never invalidate the power of Born This Way.  I don’t want to be your fucking queen, I want to be your friend.”
