On Sunday (16 October), Kylie took to Snapchat to give us a behind the scenes glimpse at King's ultra-cool birthday bash and she brought two-year-old niece North along, too.
But it looks like little North - who is already a dab hand with a make-up brush - soon got a little bored with the bouncy castles, ferris wheels and go-karting games as she began to raid Kylie's ever growing Lip Kit collection inside the house!
The colour she chose? Dead of Knight - a striking carbon black, of course!
In one of Kylie's weekend Snapchats, mischievous North can be seen playing around with the Lip Kit box before opening it up and asking asking aunty KJ to put it on her lips.
Double checking that's the shade North really wants Kylie asks, "You wanted black, yeah?!"
As the Keeping Up With The Kardashians star begins to apply the in-your-face shade, she says, "Oh, your little lips! Do you like it?" to which North replies a super happy, "Yeah!"
We always knew she was a total trendsetter. She could also teach us a thing or two about pouting, right? Just look at that little face!
After slathering North's lips with the hot new hue, Kylie posted a snap of the tot and a pal holding two Lip Kits from her current collection. She captioned it, "What happens at aunty Kylie's stays at aunty Kylie's."
Level of cute = too much to handle.
This isn't North's first venture into the world of beauty, though, as mum Kim revealed that although she has hundreds of toys to play with, she'll almost always opt for the nail polish instead.
A girl after our own hearts!
