Kim Kardashian shocked fans as she reveals biological parents of her surrogate baby

For the first time Kim has admitted secret details about her pregancy.

Kim Kardashian dropped a bombshell after revealing a secret detail about her pregnancy that fans weren't expecting.

Since welcoming baby number three with husband Kanye West, the public have been speculating on whether the parents were in the room during the delivery of their child, what the baby's name is and even a crazy rumour that sister Kylie is the secret surrogate.

But Kim threw a curveball when she revealed to fans that she did not actually have a 'surrogate' pregnancy in the traditional sense, as fans had believed.

Kim had been forced to look for alternatives after being told how it had been unsafe for her to carry a third baby as she struggles with high risk conditions preeclampsia and placenta accreta.

Although Kim has repeatedly referred to the woman carrying her child as 'her surrogate' what she actually had was a 'gestational carrier' - meaning her newborn daughter IS biologically both hers and Kanye's.

Speaking via her app , Kim explained: "A traditional surrogate donates her egg, is artificially inseminated with the father's sperm and then carries the baby to term.

"Since we implanted my fertilized egg in our gestational carrier, our baby is biologically mine and Kanye’s," she confirmed. Adding: "You can either choose someone that you know or you can go through an agency, like Kanye and I did,"

The Mirror reports that the now mum-of-three was also keen to point out that although she didn't carry the baby herself, the process was in no way 'an easy way out.'

"It’s not for everyone, but I absolutely love my gestational carrier and this was the best experience I've ever had," she said.

"Our gestational carrier gave us the greatest gift one could give. The connection with our baby came instantly and it's as if she was with us the whole time. Having a gestational carrier was so special for us and she made our dreams of expanding our family come true.

"We are so excited to finally welcome home our baby girl." she added.
