Victoria's Secret supermodel Alessandra Ambrosio is pregnant again, a rep for the stunning, leggy model confirmed with Us Weekly.

The baby is the second for Ambrosio and her fiance California businessman Jamie Mazur. They have a 3-year-old daughter name Anja.

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

Ambrosio reportedly told Brazilian magazine Istoe Gente that she is four months pregnant. The 30-year-old model is originally from Brazil.

Us Weekly said that Ambrosio surprised her long-time fiancé with the baby news on his birthday in September.

If Ambrosio is already four months along, that means she did a good job of hiding it while working the catwalk last month at the annual Victoria's Secret fashion show.

The pregnant model even wore lingerie and she looked flawless.
