“They just found out,” a source tells the publication. “Kourtney is so thrilled; she had wanted a girl from the very start.” (Though, at first, the same could probably not be said about Scott.)
As seen in the new teaser for Kourtney and Khloe Take the Hamptons, the mom-of-two finds out about the sex of her third baby on the upcoming E! spin-off. So nautrally, fans will just have to wait for that show to premiere in order to get the official gender confirmation.
