She encouraged her son to “stick with it” as people wouldn’t judge him for showing how “creative and amazing” he is, before reassuring him lots of other guys wear nail polish.
She added: “That made him feel better, but it just got me to thinking how completely judged we are all the time.”
The 38-year-old star — who has Genesis and 9-year-old son Egypt with husband Swizz Beatz — admitted the incident had made her reflect on how “concerning” it is that people feel they need to keep parts of themselves hidden away.
She said: “The way I see it, there is masculine and there are feminine energies inside of us all, period. It gets concerning to me that we can’t just explore these different sides of ourselves. These different energies that are within us.”
Keys admitted she often expresses “the masculine energy” inside herself and feels judged.
She said: “And, all the time, if that happens, there are the judgments, and there’s the stereotypes, and there are all the energies that come towards that.
“And for my boys, [it’s] similar, if they want to express the feminine energy that’s inside of them. There’s all of these judgments, and all these rules, and stereotypes, and vibes.”
The “Fallin” hitmaker feels “really, really frustrated about it.”
She added: “I ask myself, ‘Why is that? Why can’t we just express the different energies that are inside us?’
“We should be able to explore and express [our masculine and feminine energies] however we want to.”
