The Kardashian kids never stop!

On Friday, hours afterKim Kardashian Westannounced the nameof the newest addition to her andKanye West‘s brood,their son Psalm, the mother of four hosted a movie screening for her children, their cousins and friends.

The group — which included Kardashian West’s kidsNorth West, 6 next month,Saint West, 3, andChicago West, 15 months, as well asMason Disick, 9, andReign Disick, 4, — all enjoyed a screening ofThe Secret Life of Pets 2, which hits theaters next month.

“We are having aSecret Life of Pets 2screening tonight at the house with all of my kids and their cousins and friends and we are so excited to see this movie,” Kardashian West, 38, explained in an Instagram Story.

The kids also received an elaborate three-tiered cake decorated with all of theSecret Life of Petscharacters — and there was even a canine-friendly cake forNorth’s dog Sushi!

Mason then showed off his athletic skills as he hit a baseball bat relentlessly against a bumblebee-shaped piñata. Once all of the candy had fallen out of the piñata, the kids ran to collect it, with a little help from Kardashian West’s husband.

“Babe, it’s for the kids!” Kardashian West can be heard saying to West, 41, in the background of one Instagram Story video, as West picks up candy along with his children. “She wanted me to help them,” West explained, and Kardashian West laughed, saying, “Oh, I thought you were taking it!”

Once they were settled in to watch the movie, the fun didn’t stop. As the opening credits rolled, another Instagram Story video showed Saint, Mason and Reign dancing in front of the screen until Kardashian West yelled, “Sainty, move! Mason!”

TheKeeping Up with the Kardashiansstar revealed the name in the form of a text conversation with her husband.

“Beautiful Mother’s Day with the arrival of our fourth child. We are blessed beyond measure. We have everything we need,” the message read. Kardashian West captioned the image “Psalm West.”

“Kanye has been going through a spiritual revival lately. Every name has a meaning that is personal between Kanye and Kim and the child,”a source close to the rapper told PEOPLEon Friday, adding that the proud dad had some name ideas “weeks ago” before Psalm’s arrival on May 10.

“Psalm is a good reflection of where Kanye and Kim are spiritually,” the source added of the name, which means “song” in Hebrew.

“Kanye is very involved in choosing the names. He and Kim do exactly what every couple does, where they each bring up names and the other one gives their feedback. It’s very traditional that way,” the source said. “Kanye would never just choose a name that Kim doesn’t like, or vice versa. The names are things that they mutually agree upon.”
