Brazilian supermodel Alessandra Ambrosio and fiancé Jamie Mazur welcomed baby Noah Phoenix into the world on Monday, giving the couple’s daughter Anja a little brother.

The couple made the announcement of baby Noah’s birth on both Twitter and Facebook, saying, “Well, the day just arrived and we couldn’t be more happy!!! Noah Phoenix was born yesterday afternoon and already stole our hearts. Anja is a proud big sister now and we are so thankful he is with us…”

Just this weekend, the proud parents were thrown a baby shower in Brazil, with the Victoria’s Secret Angel posting photos on Twitter, saying, “So much fun at my little [boy’s] baby shower !! Now just have to wait for him to arrive!!!”

(She clearly did not have to wait long.)
