For those of you not familiar with JoJo Siwa, she the reason for children all over Ireland wearing giant hair bows.
The former Dance Moms star, current Youtuber, mini-mogul and pop star is one of the biggest hits on the internet.
Even Kardashian heiress North West counts her as an idol.
So, when parents Kim and Kanye were looking for a new babysitter, the 15-year-old jumped to the top of their list.
The reality star’s eldest child arrived at Swisa’s insane house dressed head-to-toe JoJo and ready to make slime.
“You know my number,” Kim said to North, as she prepared to leave her for the day, which North replied, “I don't know your phone number” but as she did know her phone password she proceeded to tell everyone in the room what it was.
JoJo promised North a fun day, which was filmed for both Siwa’s YouTube channel and an upcoming episode of Keeping Up With The Kardashians.
The seven-minute vlog sees the duo play hide-and-seek, make a glittery mess with slime and visit the star’s bedroom, which of course, has a slide.
One point Siwa opens up a claw machine, that just casually in her house and lets North West have at the toys inside - as you do.
At the end of the day, JoJo gifted North with a ticket to her concert and told her she can invite whoever she wanted to come with her.
According to Kim Kardashian, her “baby girl North had her dream of life come true”
