Rihanna and ASAP Rocky, two of the most influential figures in music and fashion, recently pulled out all the stops to celebrate their eldest son RZA's fourth birthday. The event, held on May 13, 2026, was a slime-themed extravaganza at the renowned Sloomoo Institute, a venue dedicated to the sensory joy of slime. According to representatives of the institute, the couple rented out the space for a private party that included custom slime-making stations, interactive installations, and the iconic “Sloomoo Falls” where guests could literally drown in slime.
Rihanna, the global pop superstar and beauty mogul, and ASAP Rocky, the acclaimed rapper and fashion icon, have always been known for their extravagant celebrations. This party was no exception. The theme was inspired by RZA's love for slime, a common childhood fascination that the couple elevated to an art form. The Sloomoo Institute, which originated in New York City and has locations in other major cities, specializes in hands-on slime experiences, making it the perfect venue for a four-year-old's birthday party.
The event featured multiple rooms with different slime textures, colors, and scents. Guests were able to create their own slime concoctions, adding glitter, foam beads, and even scented oils. The highlight was the “Sloomoo Falls,” a vertical slime cascade where partygoers could stand under and get drenched. In a moment that quickly went viral on social media, Rihanna herself took part, allowing herself to be covered in slime alongside her children. This was dubbed a “Mom-of-the-Year” moment by fans, showcasing the singer's willingness to fully immerse herself in her kids' joy.
Rihanna and ASAP Rocky have three children: sons RZA, born May 13, 2022, and Riot, born in 2023, and a daughter named Rocki, who is just eight months old. The family of five was seen in various clips posted on fan pages, singing “Happy Birthday” to RZA around a custom cake designed to look like a slime bucket with the number “4” on top. The cake was a fondant creation that matched the slime theme perfectly, with green and blue swirls that resembled actual slime.
Insiders revealed to Page Six that the decorations were “over-the-top,” including balloon arches and thematic centerpieces. The source stated that the bash was “epic” and that everyone, from the children to the adults, had the time of their lives. The party also included a variety of activities for kids, such as slime-making competitions and a slime obstacle course. Entertainment was provided by a children's musician who performed interactive songs, and there were also face-painting stations and a photo booth with slime-themed props.
Rihanna and ASAP Rocky have been together since 2020, though they were friends for years prior. Their relationship has been a subject of intense media interest, particularly because both are at the top of their respective fields. Rihanna, born Robyn Rihanna Fenty in Barbados, is one of the best-selling music artists of all time, with hits like “Umbrella,” “Diamonds,” and “Work.” She also revolutionized the beauty industry with Fenty Beauty, known for its inclusive range of foundation shades. ASAP Rocky, born Rakim Mayers in Harlem, New York, is a critically acclaimed rapper whose albums like Long.Live.A$AP and Testing have defined modern hip-hop. He is also a fashion icon, frequently collaborating with brands like Dior and Gucci.
The couple's parenting style is often described as hands-on and fun-loving. They prioritize family time despite their busy schedules. Rihanna has spoken in interviews about how becoming a mother changed her perspective on life and work. She once said, “Nothing matters more than my kids. They are my everything.” ASAP Rocky has echoed similar sentiments, noting that fatherhood has made him more grounded and focused.
The slime-themed birthday party is part of a trend among celebrities to host unique and personalized events for their children. For example, Kim Kardashian and Kanye West once threw a massive carnival-themed party for their daughter North, while Beyoncé and Jay-Z have celebrated their twins with elaborate beach parties. Rihanna and ASAP Rocky's choice of a slime venue highlights their desire to give their children memorable experiences that are both fun and interactive.
Beyond the party itself, the event also raised awareness about Sloomoo Institute, which was founded by two sisters who wanted to create a space where children and adults could explore the tactile and calming properties of slime. The institute has been praised for its focus on sensory play, which can be beneficial for children with autism and other sensory processing disorders. Rihanna and ASAP Rocky's endorsement of the venue may have introduced it to a wider audience.
In addition to the party details, the couple's life has been full of milestones. Rihanna recently released new music after a long hiatus, and ASAP Rocky has been working on a new album. They have also been involved in various philanthropic efforts, including Rihanna's Clara Lionel Foundation, which supports education and emergency response programs around the world. ASAP Rocky has been involved in community outreach in Harlem, focusing on youth empowerment and the arts.
The birthday bash for RZA was not just a celebration but also a reflection of the couple's values: creativity, family, and joy. The images and videos from the event show a happy family covered in slime, laughing and enjoying each other's company. It was a day that RZA will likely remember for years to come, and it set a high bar for future birthday parties in the family.
As the children grow, Rihanna and ASAP Rocky are likely to continue blending their public personas with their private family life. They have managed to maintain a relatively low profile despite their fame, often sharing only curated glimpses of their home life. However, events like this birthday party offer fans a sweet and genuine look at the couple's dedication to their children.
Overall, the “epic” slime-filled bash was a perfect embodiment of Rihanna and ASAP Rocky's approach to parenting: loving, creative, and a little messy. Whether it was the custom slime stations or the drenching at the Sloomoo Falls, every detail was designed to maximize fun and create lasting memories. For RZA, turning four was a slimy, happy affair.
