Kardashian, 32, gave birth to her first child, North West, with rapper boyfriend on June 1, reported Us magazine.
"Kim sort of explained it to me. She said North is the highest power. And their baby North, their little girl, is the highest point and power between the two of them. So I thought that was really cool," Jenner said.
The 'Keeping Up With the Kardashians' star said that she was not involved in helping her daughter choose the name of her third grandchild.
