Award-winning singer Alicia Keys branded anyone who does not class themselves as feminist, as "crazy".
Speaking to Elle UK, the mother-of-two, 35, said she understood the concept to be "about owning your own power, embracing your womanhood".
The Empire State Of Mind Pt. II singer looked up an official definition of the word and said: "'The advocacy of women's rights on the ground of political, social and economic equality,' so yes.
"Yes, I am a feminist, and whoever isn't is crazy."
Describing the most influential women in her life she said her mother was at the top of the list because she was "almost too giving," as well as a number of female artists and her own sister.
Alicia is set to feature make-up free on the magazine's cover, after she explained how she no longer feels tied to expectations about her appearance, but rubbished claims that she is on a "crusade".
"It took me forever to get this skin, " she said.
"I mean, I know how it feels to have a face full of bumps and pimples. I lived through that in the public eye.
"But when I first got pregnant (with her son, Egypt, six years ago) I started to eliminate dairy from my diet and drank a lot more water, which made a huge difference to my skin.
"Some have called this a crusade. Well, I died laughing at that. I used to feel the pressure to appear as the music industry expected, but I don't now."
A stepmother to her husband Swizz Beatz's three children, Alicia added her views on the complexity of family life.
She told the magazine: "I have a very blended and interesting perspective of what family life looks like.
"There is no one way, no perfect way. Each way is different with beautiful scope to be something good. That is life.
"Our eldest son is 16 and it's really cool to be in his life as an adult figure who is not his mum, and he gives me a prelude to what is coming with my children."
