She said: "Yes, he was [an incredible lover]. I'm not going to lie." And Madonna was just as confident about her own sexual prowess. Asked if she asked him how she compared to his past lovers, she said: "I have confidence in my skills." The 'Heartbreak City' hitmaker also admitted her song 'Vogue' was inspired by Warren's colourful love life and written in just a few hours. She said: "I had seen people 'voguing.' Warren asked me to write a song for 'Dick Tracy' and I was thinking about all of the movie stars. Warren grew up in that era and he dated all of Hollywood, basically."
