Thursday's episode saw the mother-daughter duo visiting designer Olivier Rousteing in Paris. During their visit, Kim explained how the fashion mogul indirectly had something to do with North's conception.
Apparently, Kim was wearing a blue gown designed by Rousteing, 36, on the night she conceived North with ex-husband Kanye West.
"Northie, I've known Olivier since before you were a baby," the SKIMS founder told North in the episode. "And he gave daddy this blue dress that daddy wanted for me."
Kim revealed that North was actually conceived on an extra special day.
"It was my birthday the year before you were born and I wore the dress, and I got pregnant and you got in my belly the night I wore that dress," she shared. "So, Olivier might have a little something to do with the reason you're on this planet."

The Hulu series then showed a glimpse into the past, featuring Kim wearing the royal blue gown to the 2012 Angel Ball. The event took place on Oct. 22 — just one day after Kim's birthday.
The conversation between Kim and North wasn't the only baby talk on Thursday's episode of The Kardashians. Khloé Kardashian introduced her still-unnamed baby boy to big sister True Thompson, while Kylie Jenner teased her second baby's name could be revealed during season 3 of the series.
