It's claimed Madonna's latest single has been copied from a track by a Brazilian musician.

Joao Brasil claims the chorus of Give Me All Your Luvin', which she performs with Nicki Minaj and M.I.A., is a rip-off of his own tune L.O.V.E. Banana.

His record company bosses and legal team are now considering whether to take court action over the allegation - but Brasil is adamant Madonna is his heroine and he doesn't want to sue her.

"I still don't understand what happened. I'm a huge fan of hers. If it's plagiarism, then even better," he tells Brazil's Folha da Sao Paulo newspaper.

"She is always at the cutting edge of music, so it's a good sign about what I do... It's in their hands, they're looking at how to proceed and what they can do. But personally I don't want to do anything. The last thing I need in my life is a fight with Madonna" he said.
