Looking radiant, the reality star was a regal mama at the bash, hosted by Amazon Baby Registry at the Hotel Bel Air.

Sisters Kim Kardashian, Kourtney Kardashian, Kylie Jenner and Kendall Jenner, plus proud mother Kris Jenner, were all on hand to enjoy the day in the Grand Ballroom, which was packed to the rafters with playful pink balloons and pink neon signs announcing, "Baby Thompson."

Khloé, 33, seemed to love her party, captioning a gorgeous Insta pic with sis Kourtney, "Had the most unbelievable baby shower - we felt so much love! #ad So grateful to be surrounded by a beautiful support system. And special thank you to @Amazon for helping me bring it all together! More pictures to come!"

Guests included Jen Atkin, Maria Menounos, Kyle Richards and more, all of whom had a chance to pose in the photo booth with props, including pink crowns and a pacifier.
