Rihanna and A$AP Rocky went all out to celebrate their son RZA’s fourth birthday with a vibrant slime-themed party in New York City. The couple transformed the Sloomoo Institute into a private celebration space on May 13, 2026, complete with interactive slime stations, colourful installations, and the venue’s signature “Sloomoo Falls,” where guests stood beneath cascading slime.

Photos and videos shared online captured the singer enjoying the festivities alongside kids dressed in protective gear, as well as moments of guests singing “Happy Birthday” and a themed cake featuring a giant number four and a slime bucket design.
The couple arrived in coordinated neutral outfits with their three children — RZA, Riot, and baby Rocki — adding to the stylish yet playful atmosphere. Over the years, they have become known for staging elaborate, experience-driven birthday celebrations, including RZA’s second birthday at New York’s Color Factory in 2024.
Despite their global fame, Rihanna and Rocky continue to focus on fun, family-centred moments, often sharing glimpses of their home life while balancing busy careers. RZA’s slime-filled celebration further reflected their preference for creative, hands-on parties that prioritise joy and togetherness.
Overall, the celebration reflected the playful and family-focused approach Rihanna and A$AP Rocky have become known for, turning major milestones into immersive, joy-filled experiences for their children. With its colourful chaos, hands-on activities, and shared moments of fun, RZA’s fourth birthday stood out as another memorable chapter in their growing family life.
