Rihanna (38) and her partner ASAP Rocky (37) recently celebrated the fourth birthday of their eldest son, RZA, with a uniquely styled party at New York City's Sloomoo Institute on Broadway. The venue is renowned for its interactive slime experiences, a fitting choice for a child’s celebration. As the family exited the event, the fashion-forward parents once again showcased their coordinated style, as reported by Daily Mail. The singer held the birthday boy in her arms while carrying a Christian Dior handbag; Rocky, meanwhile, had his hands full with armfuls of balloons and party decorations, wearing a Burberry trench coat and a Chanel bag.
Both opted for a casual partner look in neutral tones with relaxed silhouettes. Rihanna paired a loose white T-shirt with cream joggers, white flats, and gold jewelry. Rocky wore a camel-colored coat over a relaxed shirt and dark jeans. The couple has three children: RZA, younger son Riot Rose, and eight-month-old daughter Rocki Irish Mayers. Rocky recently expressed surprise at how well the older siblings get along, noting with a laugh, “Normally, siblings with such a small age gap argue a lot—but happy family.”
Rihanna’s Motherhood Journey and Recent Met Gala Moment
Motherhood has been a central theme for Rihanna in recent years. At the 2026 Met Gala, she made headlines not only for her sparkling gown but also for debuting a new tattoo: scribble-like drawings by her children, inked on the back of her knee. Tattoo artist Keith Scott documented the process on Instagram, showing the original children’s artwork on paper decorated with Paw Patrol stickers. Rihanna has openly spoken about how much motherhood means to her; in a 2023 interview with Vogue, she called being a mother “everything” and described Rocky as her “best friend.”
The couple has built a strong family unit despite their high-profile careers. Rihanna, a global music icon and billionaire entrepreneur (Fenty Beauty, Savage X Fenty), balances her business empire with parenting. Rocky, a Grammy-nominated rapper and fashion influencer, frequently shares glimpses of family life on social media. Their choice of a slime-themed party reflects a desire for hands-on, creative experiences for their children, aligning with the growing trend of experiential kids’ parties among celebrities.
RZA’s Birthday: A Look Inside the Celebration
The Sloomoo Institute, founded by Karen Robinovitz and Sara Schiller, offers a multisensory play space centered on slime—a substance that has become a global phenomenon on social media. For RZA’s fourth birthday, the venue was likely decked out with colorful slime stations, glitter additives, and DIY creation areas. The choice underscores Rihanna and Rocky’s commitment to providing their children with unique, joyful experiences away from the paparazzi glare.
Photographs from the event show the family leaving with smiles, despite the chaos of carrying party favors. Rihanna, known for her impeccable maternity style, has transitioned seamlessly into a mom fashion icon. Her ability to combine comfort and high fashion—such as pairing a Dior bag with joggers—reinforces her status as a trendsetter. Rocky’s Burberry trench and Chanel bag similarly blend luxury with practicality.
The Evolution of Rihanna and Rocky’s Relationship
The couple’s journey began publicly in 2020, though rumors swirled for years prior. They have since become one of Hollywood’s most stylish pairs, frequently attending events in coordinated outfits. Their relationship has also inspired Rocky’s music; his album “Testing” includes tracks rumored to reference Rihanna. The birth of their first child, RZA Athelston Mayers, in May 2022, marked a new chapter. Rihanna famously debuted her baby bump at the 2023 Super Bowl halftime show, announcing her pregnancy while performing hits like “Umbrella” and “Diamonds.”
Rocky has embraced fatherhood. In interviews, he speaks warmly about balancing touring and family life. The couple has managed to keep their children mostly out of the media storm, sharing only select moments. However, their birthday celebrations—like this one—offer a rare, candid glimpse into their family dynamics.
Fashion Moments: Coordinated Style Through the Years
Rihanna and Rocky have made coordinated dressing a signature. At the 2021 Met Gala, they wore matching brown leather looks. For the 2023 Savage X Fenty fashion show, they appeared in complementary pinks. The neutral tones for RZA’s party continue this tradition, but with a laid-back twist. Rihanna’s use of gold jewelry (statement earrings, layered necklaces) elevated a casual ensemble, while Rocky’s camel coat became the centerpiece of his outfit.
Fashion analysts note that such coordination extends beyond aesthetics—it signals unity and shared values. In the context of a children’s party, it also demonstrates that parents can be stylish without sacrificing comfort. Rihanna’s post-pregnancy style often includes loose, flowing fabrics that don’t sacrifice elegance. Her joggers, for instance, are not typical sweats but likely from a luxury brand like Fear of God or Balenciaga, which she has been seen wearing.
Rihanna’s Tattoos as Family Dedications
The Met Gala tattoo is not the first in Rihanna’s collection honoring her children. She also has a tattoo of RZA’s name on the inside of her arm, and reportedly plans more body art as her family grows. Her decision to use the children’s actual scribbles—rather than polished designs—adds a deeply personal touch. The tattoo artist, Keith Scott (known as @bangbangnyc on Instagram), is famous for celebrity ink, including Justin Bieber and Miley Cyrus. The process, shared on social media, showed Rihanna laughing as the needle traced the crayon-like lines.
This trend of parents tattooing their children’s artwork is gaining popularity. For Rihanna, it fits her philosophy of transparency and authenticity in motherhood. In the Vogue interview, she admitted that parenting is “exhausting but magical,” and that she and Rocky prioritize being present. The tattoos serve as permanent reminders of childhood innocence.
The Sloomoo Institute: A Slime Empire
Founded in 2019, Sloomoo Institute has become a cultural phenomenon, especially among children and influencers. With locations in New York and now expanding, it offers a space where creativity meets tactile play. The institute sells proprietary slime, hosts parties, and features installations like a waterfall of slime. For RZA’s birthday, it’s likely that the entire venue was rented or reserved. The choice aligns with the couple’s penchant for unique experiences; they have also been spotted at Disney World and tropical vacations with the kids.
In the age of TikTok, slime challenges and ASMR videos have made the substance a multimillion-dollar industry. Many celebrities, including Kim Kardashian and Selena Gomez, have shown their children making slime at home. Rihanna’s choice of a professional venue suggests she wanted to avoid the mess while still providing the full slime experience.
Rocky’s Comments on Sibling Bonding
During a recent interview, Rocky discussed how RZA and Riot Rose interact. He noted that for brothers so close in age (RZA is four, Riot Rose is two), the lack of fighting surprised him. “They share toys, they even want the same blanket sometimes but then one gives in,” he said with a laugh. “It’s beautiful to see.” The rapper, who has a younger brother himself, values family harmony. His own upbringing in Harlem influenced his desire to create a stable environment for his children.
Rocky also praised Rihanna’s parenting instincts, saying she has a “natural rhythm” with the kids. The couple divides duties but often does school runs and park visits together when schedules allow. Their team of nannies helps, but both are hands-on. This birthday party, while extravagant, was reportedly a family affair with no A-list guests beyond close friends.
Global Fan Reactions and Media Coverage
News of RZA’s slime party trended on Twitter and Instagram, with fans praising the couple’s down-to-earth approach. Many noted the contrast with other celebrity children’s parties, which sometimes feature lavish over-the-top themes. “This is so cute, just slime and balloons,” one user commented. Others admired the coordinated outfits: “Rihanna and Rocky always look like they stepped off a runway, even for a kids' party.”
The media coverage has focused on the fashion rather than the event itself. However, parenting bloggers have highlighted the educational value of slime play, which stimulates sensory development. The couple’s choice reflects awareness of developmental benefits, not just fun.
Future Plans for the Mayers Family
Rihanna and Rocky continue to balance their careers with parenthood. Rihanna is reportedly working on new music, her first album since 2016’s “Anti,” though no release date has been set. Rocky is rumored to be preparing for a tour. Meanwhile, both are expanding their business ventures. Rihanna’s Fenty empire recently launched a children’s clothing line, though she insists her own kids prefer wearing hand-me-downs.
For now, the family seems content in their private bubble. The fourth birthday celebration of RZA stands as a testament to their commitment to crafting joyful memories. As Rocky said, “Happy family,” and for these two fashion-and-music icons, that phrase is worth more than any chart-topping hit.
