The Brazilian beauty, 30, broke the news to Brazilian magazine Istoe Gente. "I'm going to be a mom!" Ambrosio exclaimed. The baby-to-be will be the second for Ambrosio and California businessman Jamie Mazur, her longtime fiance, who are already parents to daughter Anja, 3.
She adds to the mag that she is four months along -- she surprised her man with the happy news (and a positive pregnancy test!) on his birthday in September -- but does not yet know the gender of their child.
The stunner kept her baby-to-be (and her bump!) under wraps while strutting the catwalk just last month in lingerie for Victoria's Secret annual fashion show.
