The 'Give Me All Your Luvin'' star attended the launch at Macy's, where she revealed that she had been "trying to develop a fragrance for probably the last 15 years".
She explained: "It's never worked out with various companies and different people and trying different fragrances. They never turned out the way I wanted them to smell."
Explaining that her "expensive" taste had caused problems, Madonna said: "One time I created a smell and I was told the amber, it was like a million dollars to ship from India or something... And then they tried to make [a] synthetic [version]. This happens a lot and it never smells as good as you want it to smell. That's happened a couple times."
However, with her successful partnership with Coty Prestige, she added: "Finally I got a smell I like that I can mass produce. Yay!"
Reports recently suggested that US broadcasters had requested that an advert for the fragrance be edited to make it "less suggestive".
An interview with the 53-year-old will air on ITV's Daybreak and Lorraine next week.
