Alessandra Ambrósio introduces her 7-week-old baby boy in a photoshoot shared on her Facebook page.

Ambrósio and fiancé Jamie Mazur welcomed their son on May 7. “Well, the day just arrived and we couldn’t be more happy!!! Noah Phoenix was born yesterday afternoon and already stole our hearts,” Ambrósio, 31, announced.

“Anja is a proud big sister now and we are so thankful he is with us…”

“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, wrote on Twitter.

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 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!”
