Kylie Jenner went to HUGE lengths to keep her pregnancy a secret

Unless you’ve been living under a rock in the deepest depth of the darkest forest for the past few days, you’ll be aware that Kylie Jenner has had a baby.

It was (arguably) the biggest news of the year, and we’re still crying a bit about that video.

You’ll probably be aware (unless you’ve been under the aforementioned rock since the middle of last year) that Kylie opted to keep her pregnancy a secret, and new details have emerged about how she managed such a feat.

"Keeping Kylie's pregnancy under wraps for an entire nine months was ridiculously difficult for her friends.

“It was definitely a relief when they could finally congratulate her. It was the hardest secret to keep.

“But everyone's so happy for Kylie and it's obvious that she's going to be a great mum.”

And another source added to Entertainment Tonight: "They’ve really limited who is around Kylie during this pregnancy.

"They were strategic about not being photographed and strategic about who they told."

And speaking about the day she delivered the baby girl, the source continued: "She likely used a decoy car, something the Kardashians have done a lot when trying to avoid being followed or photographed."

Kylie announced the birth of her baby last Sunday (4th February).

Taking to Instagram, she wrote: I'm sorry for keeping you in the dark through all the assumptions. I understand you're used to me bringing you along on all my journeys. My pregnancy was one I chose not to do in front of the world. I knew for myself I needed to prepare for this role of a lifetime in the most positive, stress free, and healthy way I knew how. there was no gotcha moment, no big paid reveal i had planned. I knew my baby would feel every stress and every emotion so I chose to do it this way for my little life and our happiness."

"Pregnancy has been the most beautiful, empowering, and like changing experience I've had in my entire life and I'm actually going to miss it. I appreciate my friends and especially my family for helping me make this special moment as private as we could. My beautiful and healthy baby girl arrived February 1st and I just couldn't wait to share this blessing. I've never felt love and happiness like this I could burst! Thank you for understanding.
