Grab your favorite powder blue polka-dotted dress: We have a new royal baby to welcome. Rihanna and A$AP Rocky have reportedly welcomed their second baby to their family. Sources confirmed the happy news to People. Vanity Fair has reached out to Rihanna’s reps for comment.

The couple are already parents to 15-month-old boy RZA Athelston Mayers, whose name is a nod to legendary Wu-Tang Clan member RZA. The name was revealed to the public just shy of the baby boy’s first birthday, and all signs already point to Rih and Rocky once again keeping details of their new arrival under wraps.

According to TMZ, which cited “sources with direct knowledge,” the baby is a boy, born August 3 in Los Angeles. The name, they claim, begins with an R, in keeping with the family theme. (And that’s both by birth and stage name: Rocky’s first name is Razim, while Rihanna’s first name is Robyn. We respect a pattern.)

It also, according to unnamed sources who spoke with People, sounds like this may be Rihanna’s final pregnancy. “Rihanna feels her family is now complete,” the source said, adding that “it’s something she’s always wanted.”

The happy parents will surely reveal details on their own time, as they always have, in delightfully epic fashion. After all, consider how Mystery Baby R made their public fetal debut: Via dramatic jumpsuit unveiling with a horde of backup dancers pointing directly at Rihanna’s bump while she performed at the Super Bowl Halftime Show, Rocky enthusiastically performing the part of Instagram Boyfriend and filming every second on his phone. You have to admit, it’s about as far from the Instagram-standard mom’s pair of shoes, dad’s pair of shoes, tiny pair of shoes, ‘coming soon!’ sign announcement, and our lives are all the richer for it.

Then there’s the slow trickle of throwback photos Rihanna likes to share, including some handbra shots of her carrying an in-utero RZA, iconically captioned “rub on ya titties.” What shots will we get down the line of Pre-Mystery Baby R? The world wonders.

One thing is for certain, despite the lack of immediate details on the duo’s new arrival: Rihanna’s not like other moms. She’s a cool mom.
