Alessandra Ambrosio reveals baby boy's name

Victoria's Secret model Alessandra Ambrosio welcomed a baby boy with her fiance, Jamie Mazur, on Monday (May 7), and now she's revealing the name of the new little one joining the couple's 3-year-old daughter, Anja.

"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," Ambrosio writes on her Facebook page Tuesday.

Ambrosio told E! News in April that she wanted a name that works well in both Portuguese and English.  

"It can't be too American or my grandmother won't be able to pronounce it!" she says.

Hopefully grandma's happy.
