Rihanna and A$AP Rocky Pose with Sons RZA and Riot in First Photos as Family of Four

Rihanna and A$AP Rocky are introducing the world to their family of four.

The "Diamonds" singer, 35, and the rapper, 34, pose with their baby boys — Riot Rose, 7 weeks, and RZA, 16 months — with the fashion-forward family donning casual looks as they smile together.

In August, sources confirmed to PEOPLE that the couple had welcomed a second baby boy to the family.

The pair announced the singer's second pregnancy during her Super Bowl halftime show.

Rihanna played up the big pregnancy reveal in the opening moments of her February performance, rubbing her stomach and leaving the zipper of her outfit — a jumpsuit layered over a close-fitting bodysuit and sculpted bandeau — down to reveal her belly.

The couple hinted at their new arrival's name in the Beats Studio Pro ad directed by and starring the rapper and featuring his new single "RIOT (ROWDY PIPE’N)." The video shows Rocky working in his home studio when the "Lift Me Up" singer calls him from the other room.

"Babe! Can you go to the store? We ran out of diapers," she asked.

Rocky's run takes him to the AWGE Bodega, named after his creative agency, though he's chased by fans and paparazzi on the way there and back. In the store, he grabs a pack of diapers off the shelf — AWGEY diapers, with RZA modeling on the package.

The musical pair were close friends for nearly a decade before their longtime friendship blossomed into a romantic relationship. Since PEOPLE confirmed their relationship in November 2020, the couple has been spotted out together frequently, on dates and on vacation together.

After welcoming Riot, an insider told PEOPLE, "Rihanna feels her family is now complete. It’s something she’s always wanted."
