Kylie Jenner has revealed she and her boyfriend Travis Scott have named their newborn daughter Stormi.

The 20-year-old Keeping up with the Kardashians star and her rapper partner welcomed their first child into the world last Thursday, and in a photo shared on Instagram on Tuesday the TV personality revealed the unusual moniker the new parents have chosen.

Posting a photo of her daughter with her hand wrapped around Kylie's thumb, she wrote: ''stormi (sic)''

Kylie took to social media to confirm her baby joy over the weekend, writing: ''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.''

The new parents also shared an 11 minute video montage on YouTube with clips from the last nine months as well as throwback videos.

Kylie's family, including her sisters Kim, Khloe and Kourtney, wasted no time in sending their sibling and their new niece their well wishes.
