Rihanna and A$AP Rocky celebrated son RZA’s 4th birthday with a big party in New York City.
The proud parents held a fun celebration at the Thru Moo Institute in Soho, Page Six confirmed.
According to a source, the “Diamonds” singer and rapper “rented out the entire popular slime museum” for the night.
The party was reportedly “filled with family and friends” including her two other children Riot, 2, and 8-month-old Rocky, but no other A-listers were in attendance.
The event “also included some exaggerated balloon decorations,” officials said, noting that children in attendance “played with a variety of slime attractions, including Thru Moo Falls, a DIY slime bar, and Groove’s Groovy Globe.”
Sources said the family had the “most amazing” time at the interactive party.
“The kids spent time exploring different slime vats and creating their own custom blends at the DIY bar,” the source added.
Rihanna and the “F-in’ Problem” artist were spotted entering the downtown hotspot with their three children.
The 38-year-old “Umbrella” singer layered an oversized white T-shirt under a tan jacket. She paired the look with baggy cargo pants.
She accessorized with oversized sunglasses, a gold chain necklace, white ballet flats, and a brown leather purse.
Rocky, 37, looked dapper in a long camel trench coat over a gray T-shirt, black jeans and shiny black combat boots.
The Dior Homme ambassador also carried a caramel tote bag and looked sparkling with jewellery.
The father of three entered the facility Wednesday night with his youngest child in a baby carrier and covered Rocky’s face with a cozy blanket. The birthday boy and his brother coordinated in colorful ensembles.
Rihanna and Rocky were first rumored to be dating in 2020, after years of collaborating on music together. In November of the same year, the two made their love public and went on several romantic outings.
Two years later, the pair announced that Rihanna was pregnant and expecting their first child.
In April 2022, there were rumors that they would disband, but they put those rumors to rest and welcomed RZA a month later.
In February 2023, Rihanna shocked the world by announcing she was pregnant again during her Super Bowl LII halftime show performance. She secretly gave birth to Riot that August.
Rihanna revealed she was pregnant with her third child while walking the Met Gala red carpet in May 2025.
She and Rocky welcomed their first daughter in September 2025, making them parents to three children.
