In fact, Kim recently revealed that little Nori is BFFs with her cousin Penelope.
During a Q&A on Mobio INsider, a fan asked Kim how Mason and Penelope get along with her daughter.
"Its so cute how they all love each other so much! Penelope & North are bff!" she wrote, adding that "Mason bosses them around and is super protective."
Unfortunately for Penelope and North, whenever they do go out in public together, the paparazzi are not far behind. During a recent outing, Kim and Kourtney Kardashian tried to take their daughters for a day out and when the paps got a little too close for comfort, there was a verbal confrontation and it made poor Penelope cry.
Fortunately, the family is pretty used to fending off the pesky paps and we're sure Penelope and North will learn all the tricks of the trade by the time they're toddlers!
