After they were pictured celebrating Penelope’s 3rd birthday together, it’s becoming clear that North West and her big cousin are fast becoming best friends.
Along with hanging out at the same ballet classes, the cute twosome also love singing.
Aunt Khloe Kardashian shared the most adorable video of North and Penelope, causing Kardashian fans to collectively squeal from the cuteness.
The best friends appear to be singing together as their aunt whoops in the background.
Khloe captioned the Instavid simply with: “Like a diamond”.
Khloe, 31, was on babysitting duties as she relaxed with Penelope and North, sharing another Instagram pic of them watching a cartoon together.
With Kim Kardashian expecting her second child- a baby boy- later this year, the clan is going to have their hands full with their growing brood.
Khloe has made it no secret that she hopes to have children one day, but following her split from ex husband Lamar Odom it may be a little while before we see any baby KoKos making their appearance.
In the meantime, Khloe enjoys the company of North, Penelope, 5-year-old nephew Mason and sister Kourtney’s 7-month-old son Reign.
