Rihanna and A$AP Rocky went all out for their son RZA’s fourth birthday!

The couple rented out Sloomoo Institute, an immersive slime experience, in New York City on Wednesday evening, May 13, to celebrate their son turning 4 alongside close family and friends.
The bash featured custom slime-making stations, interactive installations and the venue’s “Sloomoo Falls,” where guests can get drenched in slime, according to a Sloomoo Institute rep.

In one especially “Mom-of-the-Year” moment, Rihanna, 38, joined the kids under the slime waterfall as guests cheered her on.
Videos from the event shared on the same account show the crowd singing happy birthday to RZA, as well as a glimpse of an elaborate birthday cake complete with the large number “4” and a bucket of slime made of fondant.

The “Umbrella” singer and the “F—in’ Problems” rapper, 37, arrived at the party in coordinated neutral-toned outfits with their three kids, including Riot, 2, and Rocki, 8 months.
Rihanna accessorized with oversized sunglasses, white ballet flats and a brown purse.
Rocky, meanwhile, wore a camel trench over a gray tee, along with black jeans and combat boots.
The duo has been known to pull out all the stops for their kids’ special days.
For RZA’s second birthday in 2024, they rented out the Color Factory, an interactive, immersive art museum in N.Y.C. built around color-themed rooms and sensory experiences.
At the time, makeup artist Jazzy B revealed that the party included toys, slides and even a ball pit in several posts shared on Instagram.
