Kourtney’s sister, Kim Kardashian, confirmed this week that Kourtney is more than halfway through her third pregnancy. She also admitted she wished they could be pregnant at the same time and that she and husband Kanye West are “trying” to give their 1-year-old daughter North a sibling.

“There's a lot of craziness in the house, so why not add pregnancy hormones to the craziness?” she asked, “It would be like a partner in crime. Someone to know those cravings that you're really going through."

In the photo Kourtney posted, the Kardashian matriarch is pregnant with her only son in 1987. She has six children; Kourtney, Kim, Khloe and Rob Kardashian and Kendall and Kylie Jenner.
