The Keeping Up With The Kardashians star has been enjoying spending time with her newborn son and has not been seen in public since his birth on 14 December, preferring to stay home with her family.
But yesterday she uploaded a picture to Instagram showing herself being interviewed in a sunny garden.
The caption read: "Back to business. Just for a couple of hours! I am not ready yet. I love hibernating."
Kourtney, 35, looked gorgeous in ripped skinny jeans and a simple black jumper, as she sat on an armchair raised above a patio in the sunshine. How amazing does that garden behind her look?!
As well as caring for little Reign, the reality star and long-time boyfriend Scott Disick are also parents to son Mason, five, and two-year-old daughter Penelope.
While Kourtney was working in sunny California, three of her sisters were over in chilly New York.
Khloe and Kim Kardashian and Kendall Jenner were all in the Big Apple this week to attend a party for family friend Simon Huck's new publicity company. Kim and Khloe also launched the new Kardashian haircare range, while Kendall attended the amfAR gala.
