What has Kim said about the surrogate - and why is it controversial?
Kim revealed she felt compelled to tell the surrogate that she was carrying her and Kanye's child - but although she claims she "loves her", she didn't invite her to her baby shower.
She said: "I just felt like I wanted, whoever's carrying my baby, like what if they weren't a fan of me or my husband? And what if they didn't want to be carrying our baby?
“I wanted to give them that choice and be proud and on the same page and I wanted a relationship with her.”
"She was really excited! She was someone that had watched the show, not like a super fan or anything that it would have been uncomfortable, but she had seen my struggle and seen how open I was about it."
Kim raised eyebrows when she admitted that she didn't invite the mystery woman to her glamorous baby shower.
She said: "I, um, I did not [invite her]. I did introduce her to my family. I introduced her to my family earlier that day.
“And, you know, I just thought, I don’t know, it was like a weird decision to have to make.
“Of course, I would’ve wanted her to be there and be a part of it.
“But I hadn’t really gone that far in explaining it to my kids yet."

What is surrogacy?
Surrogacy is the name given for a type of pregnancy where a woman carries and gives birth to another person's baby.
The surrogate mother is then expected to give up the baby at birth, so it can be raised by the couple who originally wanted the baby.
Surrogacy is often an option for those unable to have children themselves, or for same sex couples.
According to surrogacy charity Childlessness Overcome Through Surrogacy (COTS), there are two different types of surrogacy.
Traditional surrogacy: When the surrogate uses her own egg fertilised with the intended father's sperm.
Gestational surrogacy: The surrogate carries the intended parent's genetic child conceived through IVF, for which specialist doctors are needed

Kardashian told Ellen DeGeneres during her pregnancy that she had not decided on a name yet.
“We don’t have a name. At the baby shower, I was like, ‘I don’t want to play any baby games, measuring the belly — none of that will work for this time around. I just want everyone to write a name on a little tile and see if there’s something that sticks.’”
Some Twitter users had speculated that the baby could be called Chicago - the US city where West is from.

‘North, Saint & Chi,’ the star wrote.
But despite this, fans still weren’t really digging the little one’s new name…
@KimKardashian I refuse to believe that you named your baby girl Chicago… —

@feelsforsterek2 @staruins Just don’t think a name should sound like a neighborhood listed on a free map. —

But let’s give the woman a break – it’s a grower, not a show-er!
The star took to her website again earlier this week to praise her surrogate.
On her website KimKardashianWest.com, Kim penned a personal post that gave thanks to her anonymous surrogate, who she refers to as her ‘gestational carrier’.
‘I’m so grateful for modern technology and that this is even possible,’ she added. ‘It’s not for everyone, but I absolutely love my gestational carrier and this was the best experience I’ve ever had.
‘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.’

Kim Kardashian & Kanye West Reveal Baby Name
Kim Kardashian-West and Kanye West looked North for their first child's name, and for their third baby, they looked to 'Ye's hometown. Kardashian-West revealed Friday (Jan. 19) that their new baby girl is named Chicago.
The news came in a tweet that linked to Kardashian-West's subscriber-only app with two simple words: Chicago West.
West has repped for Chi-Town his whole career, so his daughter's name is a fitting tribute. This is the third child for Kim and Kanye, joining daughter North and son Saint.
Earlier this week, fans wondered if a Louis Vuitton logo posted on Kardashian-West's Instagram was a clue to the little girl's name, but it looks like it was just a shout-out to the luxury brand.
