The 32-year-old 'Keeping Up With the Kardashians' star has revealed her niece - who is the daughter of her brother Rob Kardashian and his fiancé Blac Chyna - has admitted the tiny tot is "super cute and calm" and doesn't scream or shed a tear.
Speaking on her website khloewithak.com, the blonde beauty said: "I go in to see Rob and Chyna. The baby was JUST born.
"She's super cute and calm and not crying at all!"
And the 'Strong Looks Better Naked' author has revealed Blac - who already has four-year-old son King Cairo with her former partner Tyga - is equally as calm as her daughter.
Alongside a photo of the mother-of-two, Khloé wrote: "Chyna is so calm, it's almost like nothing even happened, LOL!"

And the television personality has admitted she "can't wait" to see her 29-year-old brother "interact" with his daughter when she gets older.
She said: "It's so incredible to see Rob as a dad! I can't wait to see him interacting with Dream as she grows up."
Meanwhile, the 28-year-old model has lost 23lbs just two weeks after giving birth to her second child.
Speaking previously, she said: "39lbs go away !!! Lost 23 lbs so far !!! Goal 130 post baby weight (sic)."
And Chyna isn't the only one who wants to shed the post-baby weight, as Rob has admitted he needs to lose weight too.
The Arthur George sock designer said: "[I need to] get back on it now cuz our baby is here. (sic).
"It's time for me to lose this damn weight already. (sic). "

And the 'Rob & Chyna' stars plan to follow a "strict" diet now the baby has been born.
Blac said: "My goal is to gain, like, 100 pounds this pregnancy. I'm gonna tear it up, then I'm gonna snap back. Strict diet, waist training, detox tea and working out."
