Adriana Lima has shared the "wonderful news" that she is expecting her second baby.

The 30-year-old Victoria's Secret model is married to Serbian basketball player Marko Jaric, 33, and they are already parents to two-year-old Valentina.

She took to Twitter today to share her joy with her fans.

"Big news everyone! Marko and I are so happy to share some wonderful news with all of you! #ImPregnant," she wrote.

"My favourite job in the world is being a mom! My family could not be more happy!"

Adriana and Marko eloped on Valentine's Day in 2009 and found out soon after that she was having her first child.

The Brazilian beauty has revelled in being a mother and is thrilled to be adding to her growing family.

"The entire family is very excited, especially Valentina," she told People magazine. "She keeps blowing kisses to my belly and saying, Kisses for the baby.'"
