The Keeping Up With The Kardashians star, 33, took to social media last night (24 January) to post the incredibly cute picture and her fans were quick to post their adoring comments.
In the snap, Kourtney Kardashian's daughter Penelope - her second child with Scott Disick - is sat on a sofa dressed in a soft grey jumper. She has her arms around her cousin North, who is dressed in a white babygro and cream dribble bib.
Although proud mum Kim has begun to post more pictures of her seven-month-old daughter on social media, this is the first of the cuddling cousins who are a year apart in age. She captioned the photo: "BFF'S."
One fan commented "they are both beautiful girls and r very blessed to have such a loving family", while another wrote: "Gorgeous Nor. That look lol, just like her Daddy."
Earlier the same day, Kim had chosen to share another adorable snap - this time of herself as a child.
The reality TV star posted a flashback photo from her fourth birthday, with the message: "#FBF having my cake and eating it too #1984 #MyBday #UmmmmBabyGlam?!?"
A young Kim can be seen enjoying a slice of birthday cake, wearing a white ribbon in her hair. And it's clear where North gets her angelic looks from...
