Rihanna and A$AP Rocky are known for their unconventional style, and they brought that flair to their son RZA's 4th birthday celebration. The couple rented out the entire Sloomoo Institute, a slime museum, in New York City for the night, creating an unforgettable experience for their eldest child and his friends.
A Night at the Slime Museum
On May 13, 2026, the proud parents hosted an epic birthday party at the Soho venue. The event was attended by close friends and family, including RZA's siblings, Riot (2) and Rocki (8 months old). The celebration featured over-the-top balloon decorations and allowed children to explore various slime attractions, such as Sloomoo Falls, the DIY Slime bar, and Groov's Groovy Grove, according to Page Six. In one image shared on social media, Rihanna was seen standing under a slimy waterfall. The outlet revealed that kids spent time exploring different slime vats and creating their own custom blends at the DIY bar.
Parent-Child Matching Outfits
For the occasion, Rihanna and A$AP Rocky coordinated their outfits to match the event's aesthetic. The 'Umbrella' singer wore a beige jacket, off-white pants, a white summer t-shirt, and brown-tinted sunglasses. Rocky complemented her look with a beige coat, a grey t-shirt, and black denim pants. Rihanna carried a maroon bag for a pop of color, while Rocky opted for a muted brown bag.
A Tradition of Creative Birthdays
This is not the first time the couple has gone all out for their children's birthdays. Last year, for RZA's 3rd birthday, they rented a color museum with interactive and immersive experiences. Make-up artist Jazzy B shared on Instagram that the party included slides, toys, and a ball pit.
