Taking to her blog Tuesday, the "KUWTK" star shared pics and details we didn't know from the June party, which was a joint celebration for North and Kourtney's daughter, Penelope, who turned six.
"We had ponies with unicorn horns, a cotton candy and s'mores station, a 'unicorn snot' glitter slime craft station and music by DJ Livia — she’s only 10 years old and she was so good!" Kim wrote, sharing a photo of North West hard at work at the glitter station.
While all the pics are great, the cutest photo had to be the one showing a smiling Kanye West holding his baby girl as she blew out the candles on her unicorn cake.
And no birthday would be complete if the guests of honor didn't have an outfit to fit the theme!
Filling us in on the cousin's wardrobe for their big day, Kim said, “North and Penelope wore matching rainbow bathing suits and we also had matching unicorn-candy-filled birthday cakes from Flour Shop."
Seems kind of strange that Kim chose Tuesday for a TBT but maybe she's trying to deflect from Kanye's most recent controversy after that epic "Saturday Night Live" rant ... or she's showing off what she bought with that cool $1 million he gifted her.
