The `Give Me All Your Luvin`` singer has invited the eccentric pop superstar 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 performwith her at Yankee Stadium. Her manager reached out to us and said Madonna would like Gaga to performwith her."
Madonna was so desperate to have Gaga, 26, join her that she even promised to give the money raised to charity.
Unluckily for the 54-year-old music legend, Gaga`s own work schedule meant she couldn`t accept her offer.
Vincent is quoted by the Daily Mirror newspaper as saying: "She really wished she could do it. She said, `If we do it, let`s donate the money to charity.` But Gaga`s committed to her own tour."
Earlier this month, Madonna dedicated her song `Masterpiece` to Gaga, telling the crowd at a performance in Atlantic City: "I`m going to dedicate this next song ... to LadyGaga. You wanna know something? I love her. I love her. I do love her. Imitation is the highest form of flattery. But one day, very soon, we`re going to be on stage together. Just you wait. You think I`m kidding? I love LadyGaga."
