Kim Kardashian gave birth to her first child on Saturday - a month ahead of her due date.
Mail Online exclusively revealed that the 32-year-old had been admitted to hospital in Beverly Hills on Saturday morning.
The reality star had taken out a birthing suite at Cedars-Sinai Medical Center - a hospital of choice among many celebrities including Britney Spears, Victoria Beckham and Jessica Simpson.
Hours later she gave birth to her baby girl.
Her partner, rapper Kanye West, and mother Kris Jenner were reportedly at her side.
Her due date was reportedly July 11 - the same day as Kate Middleton.
Kim had planned to have a C-section but after suffering an infection had decided to take the precaution of going to the hospital a few weeks early, according to X17Online.
Both mother and baby are in good health and resting, but given the early birthday, the littlest Kardashian has been placed in an incubator.
No further details have been released and the couple have not released any hint at what they will name their daughter.
The couple announced the pregnancy in December.
Kardashian has been married twice before - to musician Damon Thomas in her 20s and most recently to basketball player Kris Humphries.
On Friday night West skipped out on a listening party for his latest album in Los Angeles, prompting speculation the baby was on its way.
Several of Kim's close friends, including Scott Disick and Jonathan Cheban both attended the party.
Sources close to the couple later confirmed to Mail Online that she had been hospitalized.
Asked for this thoughts on parenthood, he said: 'One of the things was just to be protective, that I would do anything to protect my child or my child's mother... [But I haven't fully developed those thoughts yet.'
He continued: 'Well, I just don't want to talk to America about my family. Like, this is my baby. This isn't America's Baby.'
It's been a stressful week for the couple as rumours circulated at he cheated on her with a Canadian model after they met at one of his shows, though spokespeople for both Kim and Kanye vigorously deny the claims.
The happy couple: The child's birth comes just days after Kanye West's 36th birthday on June 8
The 36-year-old rapper, who celebrated his birthday on June 8, was last spotted at the Yeezus listening party in Switzerland Tuesday.He's been heavily active in promoting his new album, due out on Tuesday, and fans wondered whether he was referring to his post-Kardashian lifestyle in the lyrics to his track, New Slave.
West raps: 'I’ll move my family out the country/So you can’t see where I stay/So go and grab the reporters/So I can smash his recorders.'
Kim was last seen Wednesday in a baby bump-hugging green Top Shop dress having lunch at Casa Vega with her friend Jonathan Cheban.
On Friday her mother Kris Jenner was spotted visiting her pregnant daughter's Los Angeles mansion, possibly ready to get a head start with the packing.
Being proactive, Kris Jenner recently gushed that Kim Kardashian and her baby daddy Kanye West will be moving into her Calabasas, California abode.
This comes despite the fact that publicity-shy Kanye reportedly refused the invitation, with a source telling HollywoodLife.com he wasn't 'trying to impose on nobody.'

'Kanye came (as fathers usually do) and spent the whole time going around to greet and say hello to everyone and every few minutes he would go back to Kim, rub her tummy, and whisper to her and make sure she was having a good time,' the insider said.
'They opened gifts together, and at the end they left together.'

Dr Paul Crane, the family's doctor, laughed as he found Kim and her sisters Kourtney and Khloe, and their mother Kris Jenner all in the office excitedly waiting together.
'I don't see any pee-pees,' Dr Crane said as he tried to determine the gender, adding: 'I'm thinking it's a girl.'
'Oh my gosh! What's the percentage?' a nervous Kim was heard asking the doctor.
It's a girl! It was revealed that Kim and Kanye
were having a girl on the season eight premiere of Keeping Up With The
Kardashians on Sunday night

Kim then added that it was what her boyfriend Kanye West, who is not in attendance, 'always wanted' noting that he would be thrilled at the revelation of their baby's sex.
Kim said: 'I know that's really what Kanye has always wanted. He wanted a little girl.'
You what? But she was also horrified during the
episode when Kim revealed that she was planning on eating her placenta
after giving birth
She also shocked viewers when she told her doctor that she hopes to eat the placenta after the birth.
'Don’t you think it makes you look younger? I really want to do it,' Kim said, much to the horror of her mother Kris Jenner.
Kim would not be the first celebrity mother to eat her placenta for its nutritious benefits.
As well as reportedly helping you 'appear youthful', Chinese herbalists among others believe that re-ingesting the protective layer that connects the baby to the wall of the uterus is a great way to nourish the body following childbirth.
The placenta contains high levels of oxytocin, and as hormone levels drop after giving birth, is believed to be a good way to replace them, which can prevent postpartum depression.
