Kourtney Kardashian has revealed - via Instagram (what else?) - the name of her third child: Reign Aston Disick.
She also shared the first picture of her baby boy, captioning it, 'madly in love'.
Kourt and her long-term partner Scott Disick welcomed Reign into the world on 14 December.
He is couple’s third child together, and joins siblings Mason, 5, and Penelope, 2 - as well as his megastar cousin North West, the daughter of Kourtney's sister (and ELLE cover star) Kim Kardashian.
As if the family needed any more reason to celebrate, Reign was born on Mason's fifth birthday.
