Forget Victoria's Secret: what's Alessandra Ambrosio's?

The VS Angel -- who welcomed son Noah in May -- posed completely nude for Made in Brazil magazine's racy, oceanside spread, showing off her slender, post-baby figure during the September photo shoot.

In October, the 31-year-old mom of two (she also shares daughter Anja, 4, with fiance Jamie Mazur), opened up to Us Weekly about her seemingly instantaneous slimdown after giving birth to her little boy.

"This time I didn't really gain a lot of weight," Ambrosio admitted. "I was actually trying to be as healthy as I could. The first time I gained a lot of weight and it was hard to lose it."

The Brazilian-born beauty partially credits breastfeeding and chasing after her tots with her speedy weightloss, though she also revealed that she makes it a point to mix up her exercise routine.

"I love to do Pilates and SoulCycle and go on walks and surf at the beach," she told Us.

Ambrosio will show off her incredible post-baby bod once again during the Victoria's Secret Fashion Show Tuesday, Dec. 3, when she struts her stuff down the iconic runway in a gem-encrusted bra worth $2.5 million.
