Victoria's Secret supermodel Alessandra Ambrosio is ready to reveal her own secret: She's pregnant again, her rep confirms to Us Weekly.

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. "Family is the most important thing for me and I'm thrilled to be adding to the family," Ambrosio tells Us in an exclusive statement. "I'm fortunate to have a loving and supportive family. It's a blessing that it will soon be growing."

The Brazilian beauty, 30, told Brazilian magazine Istoe Gente 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.
