Alessandra Ambrosio: Ambrosio’s New Baby Boy, Alessandra Ambrosio and fiancé Jamie Mazur have welcomed their second child.

The Victoria’s Secret model gave birth to a baby boy on Monday in Florianopolis, Brazil, according to People.

The couple, who began dating in 2005, is already parents to 3 ½-year-old daughter Anja Louise.

“Well, the day just arrived and we couldn’t be more happy!!! Noah Phoenix was born yesterday afternoon and already stole our hearts,” Ambrosio wrote on Facebook Tuesday. “Anja is a proud big sister now and we are so thankful he is with us.”

Mazur, a California businessman, also confirmed the birth of his baby boy via Twitter, writing: “Welcome my son, can’t wait to show you around this crazy place.”

The new arrival comes just two days after Ambrosio was feted with a baby shower.

“So much fun at my little boy baby shower! Now just have to wait for him to arrive!” the 31-year-old stunner tweeted Saturday, shortly after posting a photo of herself baring her baby bump in a cropped top and long skirt on the beach.

In April, Ambrosio revealed she and Mazur were set to welcome a baby boy into their growing family. (New York Daily News)
