For context, Rihanna, Rocky, and their two sons all have names that start with “R.” Rihanna’s real name is Robyn Fenty, Rocky’s birth name is Rakim Mayers, and their adorable boys are named RZA Athelston and Riot Rose.

While not much is known about Rihanna and A$AP Rocky’s third baby—like its due date, for example, or if it’s a boy or a girl—Rocky did confirm one detail about their new addition. Speaking on Late Night with Seth Meyers alongside Anna Wintour, Rocky shared that the baby’s name will “for sure” start with the letter R.
