For context, back in February, Gisele welcomed a new baby boy with her boyfriend, Joaquim Valente. Since then, the Brazilian supermodel has been lying pretty low, having shared just one photo of the newborn in celebration of Mother’s Day back in May.

Gisele Bündchen is celebrating another year around the sun, surrounded by her loved ones. In honor of her 45th birthday on July 20, the supermodel gave fans a rare glimpse of her and Joaquim Valente ‘s baby boy — as well as her twin sister, Patricia Bündchen — via Instagram Wednesday.

The Brazilian model shares two children with her ex-husband Tom Brady, son Benjamin, 15, and daughter Vivian, 12. In February, she welcomed her third child, her first with Valente. Their baby boy’s name has not yet been revealed, but a source previously told PEOPLE that his middle name is River.
