Kourtney Kardashian and Scott Disick welcomed their third child, Reign Aston Disick back in December.

Since then we've been treated to peeks at Reign's cot, his feet, his adorable baby clothes – but as yet we haven't seen his little face. Until now!

Just minutes ago Kourtney graced fans with the first ever picture of her three month old son, sharing an image of him smiling up at her with the caption, "My little turtle dove angel baby boy Reign Aston Disick."

HOW cute?

Reign is little brother to five-year-old Mason and two-year-old Penelope, and the three have definitely all inherited their parents' good looks.

​Kourtney has definitely been having a rough time of it lately, having to deal with a newborn and two young children while her partner Scott struggles with his addiction issues.

Scott checked himself into rehab in Costa Rica two weeks ago but just days later was spotted partying in a number of nightclubs in the area.

​Kourtney has kept relatively quiet about Scott's apparent relapse, telling E! News that "he is not home yet, but he is doing well."
