Lady Gaga has snubbed fellow gay icon Madonna by refusing to perform a duet with her in New York.
The new queen of pop turned down the Material Girl's attempt to mend a rift between the superstars because she was too busy on her Born This Way Ball tour.
'Madonna called to ask Gaga to perform with her at Yankee Stadium,' Gaga's manager Vincent Herbert said, reported The Sun.
'Her manager reached out to us and said Madonna would like Gaga to perform with her.'
Herbert added: '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.'
During her performance in Atlantic City, New Jersey, Madonna hinted that the pair would perform on stage together soon, but not before accusing Gaga of ripping off her music.
The pop legend has frequently accused her younger rival of copying her track Express Yourself on her single Born This Way.
During her current worldwide MDNA tour the star has also been joking about the similarities of the two, performing a medley of both songs.
Speaking at a concert in New Zealand, Gaga said: ‘It sometimes makes people feel better about themselves to put other people down or make fun of them or maybe make mockery of their work.
‘I don’t even want to fight back, because it’s more important to me to keep writing music.’
The last time Madonna and Lady Gaga shared the stage together was back in 2009, when they had a ‘cat fight’ in a comedy sketch for Saturday Night Live.
