After being warned about her health risks, they began considering a surrogate.
Her 4-year-old daughter, North West, is a makeup fan and enjoys playing with cosmetics.
"The surrogate will have 24-hour surveillance and a super-tight security squad", the insider revealed.
Do you agree with the rest of the Kardashian family that a third child is not a good idea for Kim and Kanye?
We pay for juicy info! The initial deposit that couple will pay to the surrogate's agency is believed to be a whopping $68,850.
The pair made the decision after discovering that Kim suffered from placenta accreta - a condition that makes another pregnancy life-threatening. But Kim has been vocal about having another child and even when her pregnancies had been extremely hard for her. Kim confessed the first one was still easy, but she had a tough time through pregnancy with Saint.
'My kids are a little too young to want [to use social media] now, but I think it's so important.
"I'd just love nothing more than to expand my family and just know that I have this world at home that's safe", she said on the reality show.
Kim was the victim of a robbery in Paris last October, in which millions of dollars' worth of jewelry was stolen from her.
"I feel like I have completely perfected the under-eye circle", said Kardashian West, wearing a white tank-dress from her husband Kanye's Yeezy line during her media sit-down.
Neither Kim nor Kanye commented on the speculations over the prospects of hiring a surrogate for their potential third baby. If there is more than one baby, the surrogate gets $5000 for each additional child.
