Rihanna and A$AP Rocky went all out for their son RZA’s 4th birthday, throwing a private celebration at the Sloomoo Institute in Soho, NYC. The couple, known for their impeccable style, wore coordinating neutral-toned looks that turned heads as they arrived and departed with their children. The intimate gathering included close family and friends, with no other celebrities on the guest list.
According to reports, the duo rented out the entire slime museum for the event, ensuring a safe and exclusive environment for the birthday boy and his younger siblings. RZA, whose full name is RZA Athelston Mayers, celebrated alongside his brother Riot Rose, 2, and sister Rocki Irish, 8 months. The party featured extravagant balloon displays and hands-on activities, including exploring Sloomoo Falls, the DIY Slime Bar, and Groov's Groovy Grove. An insider told Page Six that the kids spent time “exploring the different slime vats and creating their own custom blends at the DIY bar,” and that the family had the “most epic” time.
The fashion choices of the power couple were a highlight of the evening. Rihanna, founder of Fenty Beauty and Savage X Fenty, wore an oversized layered outfit: a cropped beige jacket, cream trousers, and pointed snakeskin-inspired boots. Her signature belly-baring top was absent, as she opted for a more covered-up look. A$AP Rocky matched her muted palette in a beige trench-style coat layered over a gray rhinestone graphic tee, paired with baggy dark jeans and chunky black shoes. At one point, the rapper was seen carrying baby Rocki in a carrier while covering her with a cozy blanket, adding a touch of tenderness to the paparazzi shots. The birthday boy and his little brother Riot coordinated in colorful outfits, adding a playful contrast to their parents’ neutral tones.
The Sloomoo Institute, a unique sensory playground devoted to slime, opened its doors in 2019 and quickly became a favorite destination for families. With over 15,000 square feet of interactive slime experiences, it offers visitors the chance to create custom slime blends, slide through slime falls, and explore stations that encourage tactile play. For A-list parents like Rihanna and A$AP Rocky, renting the entire venue ensures privacy and allows their children to enjoy a day without the pressure of public attention. The couple has been known to shield their kids from the spotlight, often opting for low-key outings and avoiding red carpet appearances with them.
The birthday festivities came shortly after Rihanna addressed fresh pregnancy rumors online. Speculation began circulating when an old photo from summer 2025, originally taken when she was pregnant with Rocki Irish, resurfaced on social media. After an Instagram creator reposted the image and suggested she could be expecting again, Rihanna quickly shut the rumors down in the comments section with a humorous remark: “Is the baby in the womb with us?” She joked sarcastically, referencing a popular meme. The confusion apparently stemmed from a previously shared post from Vogue featuring the singer during her pregnancy with Rocki, whom she welcomed in September 2025. Judging from the singer’s recent tattoos and piercings, it seems she is most definitely not pregnant.
Rihanna and A$AP Rocky have been a couple since 2020, though rumors of their romance began as early as 2019. The rapper, born Rakim Mayers, and the singer, born Robyn Fenty, share three children: RZA, born May 2022; Riot Rose, born August 2023; and Rocki Irish, born September 2025. Their relationship has been a subject of intense public fascination, with fans admiring their chemistry and collaborative fashion sense. The couple has been known to match not just in personal style but also in their musical projects. A$AP Rocky appeared on the remix of Rihanna’s 2021 single “Lift Me Up,” and they have been photographed together at numerous high-profile events, including the Met Gala and Paris Fashion Week.
Rihanna’s entrepreneurial empire extends far beyond music and fashion. She became a billionaire in 2021, driven by the success of Fenty Beauty, which revolutionized the cosmetics industry with its inclusive shade range. She also launched the lingerie brand Savage X Fenty, which celebrates body positivity and diversity. In 2023, she headlined the Super Bowl LVII halftime show, marking her return to live performance after a six-year hiatus. A$AP Rocky, best known as the frontman of the hip-hop collective A$AP Mob, has also ventured into fashion and acting. He debuted his own AWGE collective’s designs and starred in films like “Dope” (2015) and “Monster” (2020). Together, they form one of the most influential power couples in entertainment, often setting trends that ripple through pop culture.
The Sloomoo Institute party is just the latest example of how Rihanna and A$AP Rocky prioritize family while maintaining their superstar status. The insider reported that the evening ended with the family leaving hand-in-hand, clearly delighted by the magical evening. No other events were planned for the day, as the couple prefers intimate celebrations for their children.
Meanwhile, fans continue to speculate about future music or fashion releases from either artist. Rihanna has hinted at a new album for years, though no release date has been announced. A$AP Rocky dropped his last studio album in 2023, and has been teasing new material on social media. In the meantime, the couple’s parenting moments remain a source of fascination, with every public appearance analyzed for clues about their family life. The coordinated outfits at RZA’s birthday bash are sure to inspire fans looking for couple fashion inspiration, while the slime-themed venue idea may spark new trends in children’s party planning.
