After the show it's the after party.

Kourtney Kardashian jetted to Las Vegas with seven girlfriends on Saturday, March 21 to host the season opener of the Marquee Dayclub at The Cosmopolitan — but her mommy duties weren't out of her mind for a moment.

While the glamorous mom-of-three, who gave birth to second son Reign on Sunday, Dec. 14, was evidently excited to enjoy a much-deserved night out on the town, she made sure she showed fans where her priorities lay, posting a photograph of her post-party breast pumping session via Instagram.

Dressed in nothing but a black undergarment, Kardashian, 35, showed off her amazing post-baby figure as she stood in her hotel room after her night out at the launch party.

But adding a new (and totally cool!) dimension to the snap, the proud breastfeeding momma held her two breast pump attachments up to her chest, showing what her next job was before bed.

"After the show it's the after party," she captioned the shot which showed her pouting impressively as she posed with the pump.

Kardashian has spoken out about her commitment to breastfeeding in the past — having fed both her son Mason, 5, and her daughter Penelope, 2.

Mason self-weaned at 15 months and at the time Kardashian admitted she was sad nursing was over. "I seriously could cry just thinking about it being over," she wrote in her blog. "I love what a beautiful experience I had with my son and just wanted to share it.”
