She shared several photos and videos from the event on her Instagram Story.

The entrepreneur, who recently reconnected with her ex Pete Davidson at the Met Gala, was also joined by her younger sister Khloe, who appeared in several photos and videos taken at the event.

Kim began by sharing a video of several Calabasas firefighters, who were invited to the event, standing in front of a vintage fire truck.

The social media figure then went to “Psalm’s fire department” and showed a large mural showing her son responding to a fire alarm.

Psalm was later seen looking at the mural, which he seemed particularly impressed with.

Kim showed off a mocktail station she set up for the event in one of her other clips.

The reality TV personality also had custom plate stickers printed that read, “Psalm turns 4!”
