Speaking to DeGeneres about her pink-themed baby shower: “People brought toys and gifts and she was opening them all up the next day and she [North] said, ‘Mum, since baby sister’s not here, I think I need all of her toys in my room and I’ll play with them and just make sure they’re all OK for baby sister.”
DeGeneres picked up on what she said and replied: “She’s a toy tester ... and you just told us it’s a girl.”
Kardashian then realised what she’d said and confirmed she’d be having another girl.
This will be her third child with husband Kanye West; they are already parents to North West, four, and Saint, who is almost two.
Kardashian continued: “North is really excited about that. [Having a brother] was a little trickier, so she’s excited.
“Let’s see if it lasts. I explained to her, ‘Four in the morning, when you come in my room, I’ll be with baby sister, I have to feed her’, so we’ll see how it goes.”
The mum-of-two also admitted the Kardashian clan are “freaking out” that the couple haven’t chosen a name for their new arrival yet.
“We don’t have a name,” Kardashian admitted. “At the baby shower I was like, ‘I don’t want to play any games, measuring the belly, that won’t work out this time’.
“I just want everyone to write a name on a little tile and we’ll see if something sticks.
“We’re freaking out. We have no name.”
It comes after the star admitted she’s finding it difficult to come to terms with another woman carrying her third child.
However, after initially happy to not go through the physical pregnancy symptoms herself, Kardashian has admitted that the “easy option” was a lot harder than anticipated.
Speaking to Entertainment Tonight, she said: “You know, it is really different. Anyone that says or thinks it is just the easy way out is just completely wrong.”
Admitting that she was struggling with another woman carrying her child, she added: “I think it is so much harder to go through it this way, because you are not really in control.
“Obviously you pick someone that you completely trust and that you have a good bond and relationship with.
“But, knowing that I was able to carry my first two babies and not my baby now, it’s hard for me.
“So, it’s definitely a harder experience than I anticipated just in the control area.”
Kardashian — who suffered with placenta accreta when carrying her children North, four, and Saint, two — is thought to have found her “via an agency” and is paying her in excess of A$60,000.
It was previously claimed Kardashian — who was told by doctors not to get pregnant again because it was too risky — had been experiencing “sympathy cravings” with her surrogate.
Ahead of the baby’s arrival in January, the Keeping Up With The Kardashians star recently threw an extravagant baby shower ahead of the birth of her little one.
Hinting she was having a girl, Kardashian transformed her house in a pink wonderland with cherry blossom trees adorning her LA home.
