Here's why Kim Kardashian and Kanye West are using a different surrogate for their next baby

American reality star Kim Kardashian and her husband Kanye West are expecting their fourth baby but with a different surrogate.

It is not the first time that the couple is getting their baby through a surrogate, but this time around it is not with the same woman who gave birth to their daughter Chicago, People reported.

"Since they had another embryo, Kim and Kanye always knew they wanted to try and implant that embryo too," a source revealed. "They hoped to work with the same gestational carrier, but it didn't work out this time. They are working with a second carrier now that is pregnant and will give birth in the spring."

The source further added, "Everything so far has been smooth, just like the last time, Kim is very involved with the carrier. Kim goes to doctor's visits with the carrier and makes sure that she has everything she needs. She is a local woman with a family. Kim's OB/GYN is overseeing her pregnancy."

The new baby is due to arrive in very early May.

It was also revealed that the 38-year-old Kardashian "always wanted four kids."

Though the KKW beauty mogul has always been candid about her fears surrounding surrogacy and how she thinks it "is so much harder" than pregnancy, she opened up in May about how it ultimately was an overwhelmingly positive experience.

The good news of the child also comes with the news of the release of Kanye West's ninth album titled 'Yandhi.
