Kourtney Kardashian had quite the weekend with friends and family as she celebrated her 36th birthday!
First, the "Keeping Up With The Kardashians" star partied the night away in Las Vegas on Saturday with longtime love, Scott Disick, at 1OAK nightclub
The mom-of-three hosted the crazy birthday bash ... and judging by her Instagram, it looks like things got pretty wild during the festivities. See some of the inside shots inside!
But the photo everyone is talking about is the one above, showing the reality star sitting on a counter as she wears nothing but a pair of leather pants and her breast pumping device. "What happens in Vegas stays in Vegas," she captioned the shot.
The star, who welcomed third child Reign Aston last December, is no stranger to a breast pumping pic or two -- and took her motherly duties very seriously, despite partying hard!
On Sunday, the birthday girl was back with her family for a more tame backyard celebration.
"Happy birthday to me! #lastbirthdaypost @untilnextyear," she captioned the sweet shot.
Surrounded by her adorable family, Kourtney holds 2-year-old Penelope, while son Mason, 5, and sister Kendall Jenner eye her delicious-looking birthday cake!
We even get a peek at the reality star's post-baby bikini body, as she dons an open denim button down on top of a high-waisted two piece.
