The Kardashians have an adorable bday celebration for North West.

It's safe to say North West had a great time on her birthday with her famous family on Monday, when the Kardashian clan and her father, Kanye West, took to the happiest place on Earth to celebrate her second birthday!

Decked out in a Mickey Mouse t-shirt and red lace ears, North was the belle of the ball, looking adorable with her Minnie Mouse-themed face painting.

"Happy birthday to my sweetest Minnie Mouse!" Kim Kardashian Instagrammed on Monday. "Thank you Disneyland for the most amazing day!"

North's party was an all-day celebration, as a source tells ET the group arrived at Disneyland at 10 a.m., and stayed until past 6 p.m. Aside from Kim and Kanye of course, Kourtney Kardashian and her kids Mason and Penelope, Kendall Jenner, Kylie Jenner, and Kylie's rumored boyfriend Tyga and his son, King Cairo, all hit the Anaheim, Calif. park.

Obviously, as Kendall, 19, and Kourtney, 36, proved, you're never too old to have fun on a carousel!
