JoJo Siwa 'Babysits' North West

Singer, YouTuber and Dance Moms alum JoJo Siwa recently played babysitter for North West.

The 15-year-old spent the day with North, the 5-year-old daughter of Kim Kardashian and Kanye West, at her colorful home.

Siwa shared a video of the experience online. North tried on bows, met Siwa’s dog BowBow, played hide and seek, made glitter slime and climbed inside Siwa’s infamous car. Siwa ended by gifting North a ticket to her concert.

"I had so much fun getting to film with North and @kimkardashian," she wrote Sunday on Instagram. "Seriously North is SO adorable and awesome, and Kim is one of the SWEETEST people ever!"

Siwa also posted a photo Saturday with North and Kardashian.

"Filming this video ‘Babysitting North West’ was SO MUCH FUN! The video is hilarious and I can’t wait for you all to see it!" she wrote.

Kardashian said that meeting Siwa was North’s dream. "My baby girl North had her dream of life come true! She got to spend the day with @itsjojosiwa #speechless #bff #Only5Once," she wrote.

In addition to North, Kardashian and West are parents to 3-year-old son Saint and 14-month-old daughter Chicago. The couple confirmed in January they are expecting their fourth child, a baby boy.

In March, Siwa won Favorite Social Music Star award at the Nickelodeon Kids Choice Awards. In the spring, she will embark on the JoJo’s D.R.E.A.M. tour, which will visit cities across the United States.
