It seems like only yesterday that we were gazing at pics of Alessandra Ambrosio's baby shower and marveling at her giant (uncovered) belly...

Oh wait. It was. And then, next thing we knew, the baby was here! Alessandra Ambrosio gave birth to a baby boy on Monday in Florianopolis, Brazil, reports People. The Brazilian model, who announced her pregnancy in December (after slyly walking the Victoria's Secret Fashion Show pregnant), knew she and fiancé Jamie Mazur were expecting a boy.

On Monday, Mazur tweeted, "Welcome my son, can’t wait to show u around this crazy place." All together now: awwww.

The couple already has a 3-year-old daughter, Anja Louise, meaning Alessandra will have her hands full. But lest you expect her to drop off the modeling radar, rest assured: she's already got her post-pregnancy gigs all lined up, including an appearance at the opening of the Victoria's Secret store in London in July.

And then it's back to the Victoria's Secret runway! Do these model-moms ever stop?

UPDATE: Alessandra and Jamie have picked a name: Noah Phoenix! "I want something that works well in both Portuguese and English," Alessandra told People.
