Psalm West’s birthday party was out of this world.

In honor of her youngest turning 6, Kim Kardashian—who is also mom to kids North West, 11, Saint West, 9, and Chicago West, 9, with ex-husband Kanye West—hosted an epic Deadpool & Wolverine-themed celebration at an arcade.

As seen in Kim’s May 25 post, the festivities included motorcycle and basketball arcade games, trampoline jumping, motocross suits for her kids and a birthday cake designed to look like a bust of Ryan Reynolds and Hugh Jackman’s Deadpool and Wolverine characters, in addition to countless red and gold balloons.

The bash—aptly titled “Psalmpool & Wolverine” in a graphic plastered to the venue’s wall—was also attended by Kris Jenner, Rob Kardashian’s daughter Dream Kardashian and Khloe Kardashian and her daughter True Thompson.

In an especially sweet move, Chicago wore a custom-designed tank top to her brother’s birthday which bore the words “Happy Birthday Psalm” under bejeweled designs of Deadpool and Wolverine’s faces.

Psalm’s party isn’t the only event Kim and her family are celebrating these days. Just four days earlier, the SKIMS founder and her loved ones commemorated her graduation from law school after six years of legal training.

To mark the academic achievement, the Kardashians hosted a small commencement ceremony and complete with place settings made from her study notes. After all, during the ceremony Kim’s legal mentor spoke to how much time and effort the 44-year-old invested into her Law Office Study Program: specifically, “18 hours a week, 48 weeks a year for six straight years.”

"That's a total of 5,184 hours of legal study," Kim’s mentor continued noted. "That's time she carved out while raising four children, running businesses, filming television shows and showing up in courtrooms to advocate for others."

Plus, Psalm made sure to pay tribute to the family’s late patriarch Rob Kardashian, who was a lawyer, by dressing in a beige suit with a blue shirt and patterned tie that was on trend in the 1990s—the height of Rob’s career.

Chicago, too, honored her mom by rocking a navy pinstriped suit similar to one Kim wore during a visit to Harvard Law School in 2018.

The attendance of her kids was clearly meaningful for Kim, as she wrote on her Instagram Stories May 21, "My babies were there to see me graduate."
