Kourtney Kardashian has revealed the name she has given her baby son - and shared the first picture of the newborn.
The US reality TV star and her husband Scott Disick welcomed their new arrival a few days ago and have now announced that he is named Reign Aston Disick.
Kourtney also posted a picture on Instagram of a tiny baby's hand in an adult's hand, and told fans she was "madly in love" with her new son.
Kourtney gave birth to Reign on December 14 - her son Mason's fifth birthday.
A source told E! News the family were "freaking out with joy" at the coincidence.
The couple also have a two-year-old daughter, Penelope.
