Rihanna and A$AP Rocky Throw Slime‑Filled 4th Birthday Bash for Son RZA in New York

On May 13, 2026, Rihanna and A$AP Rocky rented New York’s Sloomoo Institute to celebrate their eldest son RZA’s fourth birthday. The venue featured custom slime‑making stations, interactive installations and the signature “Sloomoo Falls,” where guests stood beneath cascading slime. Rihanna joined the children under the slime waterfall, drawing cheers from family and friends. The celebration also included a themed cake with a giant number “4” and a fondant slime bucket, as well as balloons and coordinated neutral‑tone outfits for the parents and their three children – RZA, 4; Riot, 2; and baby Rocki, 8 months.

The couple has previously staged elaborate birthday events, such as renting the Color Factory in 2024 for RZA’s second birthday. Their latest party underscores a continued preference for playful, immersive experiences over traditional celebrity gatherings.
