Celebrity Parents Kourtney Kardashian Really Wants You to See How She Pumps The reality star shared a photo of herself wearing a breast pump while celebrating her birthday in Vegas By Staff Author Updated on December 3, 2020 01:35 AM Share Tweet Pin Email Paul Zimmerman/Getty Kourtney Kardashian may have taken a mini vacation to Las Vegas to celebrate her 36th birthday, but that doesn’t mean she took time off from mommy duty. The mother-of-three shared a photo on Instagram of herself wearing a breast pump while posing seductively on a kitchen counter. “What happens in Vegas stays in Vegas,” the Keeping Up with the Kardashians star captioned the funny post. Kardashian gave birth to son Reign Aston in December, adding to her brood, which already includes Mason Dash, 5, and Penelope Scotland, 2½. The eldest Kardashian sister spent her Saturday night in Sin City, where she celebrated her birthday at 1 OAK nightclub with boyfriend Scott Disick and a group of friends. “I feel like because we’re all so close it just makes us stronger,” she told PEOPLE of all the changes she has experienced in the past year — which included Disick completing a stint in rehab and her step-father Bruce Jenner making headlines as he transitions from male to female. “I’m not one who loves change, but everything is going to be really positive. There’s a lot of good things.” This embed is invalid This embed is invalid — Gabrielle Olya
