Alessandra Ambrósio Welcomes a Son

Talk about a model momma: Alessandra Ambrósio delivered a son on Monday in Florianopolis, Brazil.

Her newest little one, reportedly named Noah, joins daughter, 3½-year-old Anja Louise.

“Welcome my son, can’t wait to show u around this crazy place,” fiancé Jamie Mazur, who began dating the Victoria’s Secret stunner in 2005, Tweeted Monday.

The couple announced they were expecting baby No. 2 last December, and in April, revealed that they were set to welcome a boy into the family — although Ambrósio, 31, and Mazur weren’t sure what they would call him just yet.

“[Choosing a name is] the hardest part! I want something that works well in both Portuguese and English,” she explained at the time. “It can’t be too American or my grandmother won’t be able to pronounce it!”
