Madonna wants Gaga to perform on stage with her

The 'Give Me All Your Luvin'' singer Madonna has invited the eccentric pop superstar Lady Gaga to join her on stage during her 'MDNA Tour', despite previously accusing her of copying elements of her song 'Express Yourself' in her single 'Born This Way'.
Gaga's writer-and-producer Vincent Herbert revealed: "Madonna just called to ask Gaga to perform with her at Yankee Stadium. Her manager reached out to us and said Madonna would like Gaga to perform with her."
