The 36-year-old has suffered several medical problems when pregnant with both North, 3, and 11-month-old Saint.
Model Chrissy, who is pals with Kim, has now offered her services to the reality star.
Talking to Access Holiday, the 30-year-old said: "I would be her surrogate in a second.
"I really enjoyed the pregnancy process.… I loved it. Yes, [I would do it] in a heartbeat!"
What a good friend.
Chrissy is already mum to 7-month-old daughter Luna, her first with singer hubby John Legend.
Fans will be excited to hear some news on Kim after her absence from social media since she was robbed in Paris earlier this year.
