The Kardashian family live their life in front of the cameras, and the eldest Kardashian sister has proved that she really does live each day as an open book.
Kourtney, 36, took to her Instagram to share a snap of herself posing in leather trousers and a set of breast pumps.
Wearing a ‘hands free’ bra with her breast pumps, Kourtney positioned herself on the counter of her swanky Las Vegas hotel room.
Pouting to the camera, Kourtney made it clear that she would not let something like expressing breast milk get in the way of her birthday weekend.
The mum-of-three celebrated her 36th birthday over the weekend with partner Scott Disick and the rest of the Kardashian Klan.
Kourtney appeared to be enjoying a night out on the tiles 5 months after the birth of her third child, Reign, in December.
The reality star and Scott are also parents to son Mason, 5, and daughter Penelope, 2.
