After all the build up, Kim Kardashian and Kanye West's baby daughter was born at around 1.30am on Saturday at Cedars Sinai Hospital in Los Angeles. The little girl weighed just under five pounds and was almost a month premature, according to the Daily Mail.
Although it's rumoured to begin with the letter K, so far the baby's name has not been revealed.
Kim's sister Khloe tweeted on Sunday, "I can not even begin 2 describe the miracle that is now apart of our family. Mommy/baby are healthy & resting. We appreciate all of the love."
She added, "More info will come when the time is right! Thank you all for understanding! We love you all dearly! Overwhelmed with love right now.
Khloe and Kim's mother Kris Jenner, retweeted the message and also wished rapper Kanye happy Father's Day.
On an episode of the family's reality show a few weeks earlier, suffering from a stomache infection, Kim swore she'd never get pregnant again. "It feels like I am in labour. Why is this happening to me? I hate it, I can never do this again."
Expect more information on Twitter soon from the Kardashian clan!
