Kim, 34, posted the photos on Instagram earlier today (19 November) to demonstrate the faces the little girl pulls at home and when she is surrounded by photographers.
In the first snap, Kim is holding North up to the camera and they are both straight-faced. Writing alongside it, the US reality star explained: "What we're like in front of the paparazzi..."
Kim then shared a beautiful second shot, which shows them both smiling. She told her followers: "What we're like at home..."
Last week, North was pictured grinning for the first time during a trip to the zoo, however many fans were quick to point out that she was smiling at the animals - not at her mum Kim.
Well, it seems Kim has proved the critics wrong!
Meanwhile, Kim is currently on a promotional tour in Australia and she has revealed in an interview that North is taking after her daddy, rapper Kanye West.
Speaking on Channel Nine's Today Show, Kim explained: "She goes to music class several times a week.
"Every time a song comes on she's up dancing and she tries to sing. If you are singing a song she'll try singing it along with you and it is so cute to watch."
Kim and Kanye, who married in May, welcomed North into the world on 15 June 2013.
