"The entire family is very excited, especially Valentina," Lima told People, speaking of their 2-year-old daughter. "She keeps blowing kisses to my belly and saying, 'Kisses for the baby'."
Lima and Jaric were married on Valentine's Day in 2009, and she became pregnant with Valentina soon after.
"The best job in the world for me is being a mom," said the model. "I never thought I could love so much. I always thought, does unconditional love exist? Now I know it does because I feel it."
Lima will next be seen in Victoria's Secret swim catalog, which will begin appearing in mailboxes March 28.
