Kim Kardashian gave fans a peek at her son Psalm’s incredible fifth birthday party on Saturday.

The 43-year-old makeup mogul — who shares Psalm as well as North, 10, Saint, 8, and Chicago, six, with ex-husband Kanye West, 46 — took to her Instagram Stories to share behind-the-scenes footage of her youngest’s Ghostbusters-themed extravaganza.

She documented a tour of the soiree, starting with a glimpse of the green slime-themed decorations adorning the entrance to her home, complete with a life-size cutout of Psalm dressed in a Ghostbusters uniform.

‘Ok, Psalm’s Ghostbuster party, how cute is this, it’s about to start,’ Kim can be heard off-screen during the video.

‘It doesn’t really look like him,’ a voice can be heard off-camera, as Kim replies, ‘Yes, it does Saint, c’mon.’

The 43-year-old makeup mogul took to her Instagram Stories to share behind-the-scenes footage of her youngest’s Ghostbuster-themed extravaganza

The glimpse included views of guest’s personal ‘proton packs,’ a Slimer candy station and a giant Ghostbusters tiered birthday cake.

The reality star also included a sweet snap of her holding Psalm in her arms with the caption: ‘My baby is five!’

The birthday party comes after the Kardashian clan began celebrating Psalm on his actual birth date, May 9th.

His generous grandmother Kris Jenner bought the mini-me son of Kanye a small version of a Tesla Cybertruck.

Kim boasts ownership of a sleek, full-sized Cybertruck with a hefty price tag of around $100,000, frequently spotted cruising the streets of Malibu in recent months.

This comes after Kim shared a loving post for Psalm on his birthday.

She added, ‘Thank you for being such a blessing in all of our lives my Psalmy and for putting a huge smile on my face every time we are together.’

Then The Kardashians producer shared: ‘Thank you for asking me to play musical chairs with you the other day. It really meant the world to me lol!
