Kim Kardashian West was left shocked when her daughter asked why she's famous.
North West and Kim Kardashian West
The 37-year-old reality star - who has North, five, Saint, two, and seven-month-old Chicago with husband Kanye West - wasn't prepared for the questioning from her oldest child, but she was able to quickly satisfy the youngster's curiousity and helped the little girl come to a realisation about her own life.
She recalled North had asked: "Mom, why are you famous?"
She then added to Big Boy on Real 92.3: "Oh, OK, OK. I'm going to have to explain this right now.
"I'm like, 'We have a TV show.' And she was like, 'Oh OK.' That was the first time she was like, 'Oh!' "
Kim - who rose to prominence after a sex tape featuring herself and former boyfriend Ray J was leaked in 2007 - was then asked about her daughter's own wealth, as she's been a regular on 'Keeping Up With the Kardashians' since she was born and recently starred alongside her mom and grandmother Kris Jenner in a Fendi campaign.
Big Boy asked: "Do you think North has more money than us? Like her own?"
Kim laughed and replied: "North is good."
Kim recently admitted she doesn't feel very famous because her kids have no idea about her life in the public eye.
She said: "At home I'm not known. My kids have no clue what's going on. So I don't really feel it -- I spend most of my time at home."
While North doesn't know much about film, her eight-year-old cousin Mason Disick - the oldest of Kourtney Kardashian and Scott Disick's three children - is very much aware of the family's life on camera.
Kourtney previously said: "He knows. He doesn't watch it, but I've heard him talk to his friends and say, 'I'm on a TV show called 'Keeping Up with the Kardashians'. I'm like, how does he know that?!'
"Mason calls [the crew] the filmers. He used to be like, 'Are the filmers coming? I want to show them my Legos that I'm building.' Now he's in a phase where he's like, 'I don't like when the filmers are over.' "
