Psalm West celebrated his upcoming fourth birthday on Saturday during a lavish party that was thrown by his mother, Kim Kardashian, who shared several photos and videos from the event on her Instagram Story.

The 42-year-old reality television personality went all out for her youngest son, who turns four on Tuesday, by pulling out all the stops for a firefighter-themed birthday party.

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 that had been taken during the event.

Kardashian began by sharing a video of several firefighters from Calabasas, who had been invited to the event, standing in front of a vintage fire engine.

The social media figure then entered ‘Psalm’s fire department’ and showed off a sizable mural that showed her son responding to a fire alarm.
