Kylie took to Instagram on Sunday to announce she had welcomed a daughter into the world with her partner Travis Scott on Thursday.

She shared in the accompanying post: "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 health 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 life-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."
