"He's here and he's perfect," she told fans after his May 9 arrival via surrogate.
"He's also Chicago's twin," she said of his uncanny likeness to Kim and Kanye West's third child, daughter Chicago, 16-months.
"I'm sure he will change a lot but now he looks just like her."
Kim's mum Kris Jenner agreed that her 10th grandchild does look like Chi, who was also born via surrogate in January 2018.
"[He is] the twin! The twin of Chicago! Same child," Kris gushed.
Hilariously, Kris first learned Kimye's surrogate was in labour while appearing on the Ellen Show!
"My mum doesn't even know this but Kim's surrogate went into labour, so she's at the hospital," the mum-of-four and Kim's sister Kourtney told the audience.
An excited Kris replied, "What are we doing here? Fire up the car!"
