Kris Jenner delivered her granddaughter Stormi.

The 'Keeping Up With The Kardashians' star couldn't believe how well her daughter Kylie Jenner did when she gave birth to the little girl seven months ago.

In a sneak peek from Sunday's episode of 'Keeping Up with the Kardashians', she said: ''She did really, really well. She just kept saying, 'I just don't feel any pain.' You'd see these contractions like crazy and she would go, 'I just am not feeling it.' I'm like, 'This is really weird!' She was such a trooper. She really was. She was so calm. It was really exciting. I delivered the baby! I delivered her. I pulled her out.''

Kylie didn't confirm her pregnancy until after she had given birth to Stormi.

She shared on Instagram at the time: ''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.''
