The news comes after it was reported Kimye’s 4th baby was due earlier this week but Kim was quick to silence those rumours on Twitter.
She said: ‘Wait just saw news our baby boy came but that’s not true! It’s Met Monday, I’m in NYC. I would be at the hospital lol’ (sic).
Kourtney revealed the news live on Ellen, much to the surprise of Kris Jenner, Kim’s mum, who had no idea!
The baby boy’s arrival will come a year after the couple’s last baby, Chicago, was born. Chicago was also born via surrogate but it is reported that Kim and Kanye opted for a different surrogate, following their surrogate first ruling out carrying anymore children for them.
A source told People back when the pregnancy was announced that they had “hoped to work with the same gestational carrier” but are “now working with a second carrier that is pregnant and will give birth in the spring”.
