When Cohen asked the doting grandma if she thought it was even a possibility, she said, "No, because you don't walk around saying, 'Hi, North West.' You walk around saying, 'Hi North' or whatever her nickname may end up being."
The Momager, 57, added that people "don't walk around saying, 'Hi 'Kris Jenner!'" to her.
Kris on Tuesday told Jimmy Fallon the A-listers decided upon the name North because it represents "the highest point between the two" parents.
Speaking with Cohen, Kris also denied reports that Kanye refuses to change diapers; that her daughter Kylie is dating Lil' Twist, and that she's discouraged Kim from leaving the house, so as to drum up demand for the baby's first pictures.
