Kim Kardashian and Kourtney Kardashian‘s daughters are less than a year apart…and they’re already best friends! North West’s mom took to Instagram Friday to share a rare photo of her 7-month-old and Penelope.
“BFF’S,” she captioned the pic, in which North is seated on her big cousin’s lap.
In an online fan chat last month, the reality star dished on what her daughter’s relationship is like with Kourtney and Scott Disick’s two kids. “It’s so cute how they all love each other so much!” she wrote. “Penelope & North are bff! Mason bosses them around and is super protective.”
Penelope will turn two next July, while Mason just celebrated his fourth birthday last month.
