Madonna says she is more of an "artist" than a pop star.

The singer told Love magazine that artistry involves starting "revolutions" through creativity.

She said: "I don't consider myself a pop act, I consider myself an artist.

"And it's an artist's responsibility to be revolutionary in our work. It's our responsibility, our duty and our privilege."

Madonna added that she likes to use photo-sharing platform Instagram to throw light on "issues" or certain people.

She said: "I like Instagram because it's like keeping a diary and every day I get to share different aspects of my personality, my life, and what inspires me, what infuriates me, or what causes I want to fight for.

''It allows me to be mysterious, ironic, provocative or proud. I get to use it as a platform to bring attention to people or issues that I think are important. It allows me to be the curator of my life."
