The 38-year-old singer, known for challenging stereotypes, says she wants her children - six-year-old daughter Willow and 11-month-old son Jameson - to grow up sans gender-imposed limitations.
"We are a very label-less household. Last week Willow told me she is going to marry an African woman. I was like: 'Great, can you teach me how to make African food?
"And she's like: 'Sure Mama, and we are going to live with you while our house is getting ready'," Pink tells The People.
"I was in a school and the bathroom outside the kindergarten said: 'Gender Neutral - anybody,' and it was a drawing of many different shapes.
"I took a picture of it and I wrote: 'Progress'. I thought that was awesome. I love that kids are having this conversation," she says.
