Kim Kardashian posted several photos on her Instagram account from her son Psalm’s extravagant 5th birthday party on Tuesday. The 43-year-old reality TV star hosted a Ghostbusters-themed celebration for her youngest son, who seemed to be having a fantastic time.

The entrepreneur opted for a casual look, wearing a white t-shirt and jet-black leather pants to the event. Her platinum blonde hair was left loose, cascading down her back and shoulders.

Psalm posed for a picture with his grandmother, Kris Jenner, who was dressed in a Balenciaga athletic top, leggings, and high-top Nike sneakers. He also posed next to a life-size cutout of himself in a Ghostbusters costume.

Kardashian shared a photo of Psalm’s birthday cake, topped with a decorative Slimer. Her youngest child was also seen enjoying what appeared to be a custom-made Ecto-Cooler.

The Skims founder took a photo with her youngest daughter, six-year-old Chicago, at the event. Kardashian shares Psalm, Chicago, and her older children North, 10, and Saint, eight, with her ex-husband, Kanye West.

Kardashian and the 46-year-old rapper began their family in June 2013 with the birth of their eldest child. They married in 2014 and welcomed their three youngest children in 2015, 2018, and 2019. The couple separated in 2021, finalizing their divorce the following year.
