Robyn has revealed she was banned from talking to Madonna while supporting her on the European leg of her tour.
The With Every Heartbeat singer revealed to a Swedish newspaper she and her crew given strict rules about how to behave on the Sticky And Sweet tour, reports the New York Post.
Robyn apparently said: "We were told not to approach Madonna, not to speak to Madonna and, above all, no pictures. I hadn't expected any glamour, but it's strange that they assume that the first thing you're gonna do is run after Madonna and ask for an autograph."
She added: "My worst nightmare would be to turn into Madonna. Madonna is constantly chasing the latest trends."
The Swedish popstar recently revealed she and Madonna never even met formerly during the tour.
She said: "It's very business, her management called my management, It's not like she calls you and asks you.
"I don't know how Madonna got in touch with my music but I'm told she likes it, which is cool."
