The eldest Kardashian sister, Kourtney Kardashian, is a third time mommy and finally shared a little bit of scoop on her newborn – his name!

Last Sunday, Kardashian and her long time boyfriend Scott Disick welcomed their third child together, a baby boy, the same day their oldest son Mason turned five.

The usual social media vocal family has been tight-lipped on the arrival of Kourtney’s new child but today that changed.

Kourtney Kardashian shared a first look at her newborn and revealed his name. She uploaded a photo to her Instagram page of her son’s hand; she captioned the photo, “Madly in love with my little Reign Aston Disick.” [SEE BELOW]

Reign is the third child for Kardashian and Disick. As noted above they have a five-year old son Mason and a two-year old daughter Penelope.
