Supermodel Alessandra Ambrosio is pregnant again.

The Victoria's Secret Angel is expecting her second child with her businessman fiance Jamie Mazur and the couple are thrilled with their happy news.

In a statement, Brazilian-born Alessandra said: "Family is the most important thing for me and I'm thrilled to be adding to the family. I'm fortunate to have a loving and supportive family. It's a blessing that it will soon be growing."

The couple are already parents to three-year-old daughter Anja Louise.

The 30-year-old catwalk beauty also revealed to Brazilian magazine Istoe Gente that she is four months into the pregnancy and she surprised Jamie with the news on his birthday in September.

Alessandra managed to conceal her burgeoning bump when she took to the catwalk for the annual Victoria's Secret fashion show last month.
