Growing family ... Alessandra Ambrosio.
Victoria's Secret model Alessandra Ambrosio is pregnant with her second child.
The 30-year-old Brazilian beauty has announced she's expecting another baby with longtime fiance Jamie Mazur, a US businessman.
The couple are already parents to three-year-old daughter Anja, and say they're ecstatic to be giving her a little brother or sister.
Pregnant on the catwalk ... Alessandra Ambrosio models for Victoria's Secret.
"Family is the most important thing for me and I'm thrilled to be adding to the family," Ambrosio told Us Weekly.
"I'm fortunate to have a loving and supportive family. It's a blessing that it will soon be growing."
Ambrosio told Brazilian magazine Istoe Gente she's four months along but does not yet know the gender of the baby.
She revealed that she surprised Mazur with the happy news on his birthday in September by showing him the positive pregnancy test.
Ambrosio walked the catwalk last month for the annual Victoria's Secret lingerie fashion show but didn't reveal her pregnancy for fear it would disqualify her.
"A week before, I told my booker I don't think I'm going to be able to fit into the clothes because I gained a few pounds already, but we were just quiet."
Cutting out sugar and ramping up the exercise in the lead-up to the fashion parade did the trick though and Ambrosio's pregnancy went unnoticed, the model said.
