Pretty in pink, party of two.

Rihanna and daughter Rocki Irish Mayers had a mommy-and-me moment in custom pink Dior for the tot’s first birthday party on Sunday, Sept. 13.

Both wore pale pink rompers with spaghetti straps, ruching at the necklines and legs, and oversized black-and-white polka dot bows at the back.

Rocki’s pint-sized look included a dainty chain necklace, tiny diamond stud earrings and coordinating polka dot bows in her pigtails.

Rihanna’s longtime friend Melissa Forde shared photos from the bash on Instagram. “Happyyy Birthdayyy Rocki Irish I can’t believe Auntie’s baby is alreadyyy a yearrr,” she wrote, adding, “Bday twinning wit your beautiful mama and my sestahhh @badgalriri 🥰💖💖🥳🥳🎉🎉🥳🎁🎁🎈🎈🎀🎀🎊.”

Additional clips showed the newly minted 1-year-old digging into a pastel layered cake and climbing over play structures. Pastel balloons and a kid-sized carousel rounded out the decor.

Rocki is the youngest of Rihanna, 38, and boyfriend A$AP Rocky’s three children, joining big brothers RZA, 4, and Riot, 3.

“I wanna just say this to all the girl dads out there: I’m the newest member of the club,” Rocky said at the CFDA Fashion Awards shortly after Rocki’s September 2025 arrival. “Salute me, and welcome me.”

Rih announced her baby girl’s birth on Instagram cradling the newborn (who was swaddled in pink bows) while wearing an estimated $150,000 in jewelry, including a rose gold Audemars Piguet Royal Oak watch and a custom “Mom” ring.

The couple hosted RZA’s fourth at New York’s Sloomoo Institute in May, then celebrated Riot’s third with a Spider-Man-themed fête at Rih’s Barbados home in early August.

Dior has been a house favorite since Rocki’s arrival. In April, she made her first public appearance in Paris wearing a vintage beanie from John Galliano’s tenure at the house, then landed a W magazine cover in a Dior Haute Couture diaper later that same month.

She’s since notched a second cover on W China’s Love Issue alongside dad Rocky.
