The inspiring 38-year-old recently made headlines for her passionate VMAs speech addressed to her daughter, Willow, who said she 'looked like a boy'.
"I said to her, 'Do you see me growing my hair?' She said, 'No, mama.' I said, 'Do you see me changing my body?' 'No, mama.' 'Do you see me changing the way I present myself to the world?' 'No, mama.' 'Do you see me selling out arenas all over the world?' 'Yes, Mama.' 'OK! So, baby girl. We don't change. We take the gravel and the shell and we make a pearl. And we help other people to change so they can see more kinds of beauty," she said.
