Gisele Bündchen is a boy mom again!

The Brazilian supermodel, 44, welcomed a baby boy with her boyfriend Joaquim Valente, a source tells PEOPLE, adding that one part of his name has a sweet nod to nature. Although his first name is still unknown, the insider shares that his middle name is River.

Bündchen’s son’s moniker continues her sweet tradition of her kids having water-themed middle names — she is also mom to daughter Vivian Lake, 12, and son Benjamin Rein, 15, who she shares with ex Tom Brady.

On Wednesday, Feb. 5, news broke that Bündchen welcomed her third baby, her first with boyfriend Joaquim Valente. TMZ was first to report the news.

At the time, no further details — including the sex and name of the baby — were known yet.

Bündchen has been dating Valente, a Jiu-Jitsu instructor, since June 2023.

After news broke that Bündchen was expecting again, a source close to the model exclusively told PEOPLE that she was “excited to embrace this new chapter openly.”

Bündchen “received many positive messages and congratulations,” said the insider, adding that she “wanted to keep it private for as long as she could, doing so was starting to be a challenge.”

In November, the Bündchen was photographed walking hand-in-hand with her boyfriend on the beach in Costa Rica, showing her pregnant belly as she wore a white crochet coverup and a dark bikini, as seen in pictures first obtained by the Daily Mail.

Bündchen accessorized with sunglasses and flip-flops as she strolled alongside her boyfriend, who opted for a green T-shirt, camo shorts and sandals.
