Madonna, who is currently on her 'Sticky and Sweet' world tour, has allegedly handed out strict orders asking the managing crew not to let her support acts approach her.
The 'Material' girl is said to have refused to mingle with artists who open her tour's European leg, reports China Daily.
Swedish pop singer Robyn, who performed before the Queen of Pop, revealed that the crew had conveyed them the orders not to speak to the pop singer or ask for autographs and photos.
'With Every Heartbeat' singer said: "I hadn't expected any glamour, but it's strange that they assume that the first thing you're going to do is run after Madonna and ask for an autograph."
Robyn further revealed that she hadn't even met the superstar and would hate to be in her shoes.
She added to a Swedish newspaper: "My worst nightmare would be to turn into a Madonna because of her constant chasing of the latest trends.
"As an artist I do not want to be someone who does not feel safe in the creative process."
