Madonna has told how she has never felt as loved by a man as Wallis Simpson was by King Edward VIII.
The pop queen turned film director said that she believes men "want power" and that they will "kill to have it".
But Madonna, 53, told The Radio Times that King Edward VIII - who she denied was a Nazi sympathiser and whose relationship with the American divorcee is the subject of her new film - was an exception.
The star's movie, W.E., features a modern-day American woman, Wally, trapped in a loveless marriage and obsessed with her namesake, Mrs Simpson.
The singer said: "When she (Wally) says 'I wonder what it was like to have been loved that much?' I think I probably said that to myself.
"Men want power and they will kill to have it. If you look back in history, how many wars have been waged to win the throne? And here's a man who walked away from that for love. And so for a romantic like me, I would say: 'Wow, to be loved like that!'."
Twice-divorced Madonna, whose current partner is 24-year-old dancer Brahim Zaibat, said: "What Edward gave up was huge, monumental, but I also don't think that he realised that when he abdicated he was never going to be allowed to come back into the country."
She added: "I've been asked many times if I would give up everything for love. And I think it's important to understand that with love, and in all relationships, you have to give up something."
Madonna said that she had come to film-making with "great humility" and that she'd picked up "tips" from her ex-husbands, film director Guy Ritchie and actor and director Sean Penn.
