New mom Alessandra Ambrosio admitted that she was nervous when she found out that she was chosen to model the $2.5 million Fantasy Bra for the Victoria's Secret Fashion Show this coming December.

Victoria's Secret Angel, Alessandra Ambrosio, said that she immediately felt pressured knowing that she will have the privilege to model the Victoria's Secret Fantasy Bra for the coming annual show. Considering the fact that the 31-year-old just gave birth to her second child last May, Alessandra was put on immense pressure to get back into shape.

In an interview she had with People.com, Alessandra said that she was breastfeeding when she got the call.

"I just wanted to scream. I won't lie, I was really worried. I was in total mother mode," the Brazilian model said.

The mother-of-two said that she needed to seek permission from her doctor first before she is allowed to work again. And once she had the go signal, she began with yoga and walking and later added pilates and spinning classes. She also said that her active lifestyle in Los Angeles helped her tone up.

"I was playing a lot of volleyball on the beach, swimming and running after my kids. And breastfeeding always helps," she said.

Apart from her routinely exercise, she incorporated a healthy diet to help her get back into shape fast. Alessandra said that she ate a lot of green salads, kale juice and fish.

This year's Floral Fantasy Bra Gift Set was exclusively designed for Victoria's Secret by New Jersey based, London Jewelers. It's a sexy push up bra studded with sapphires, amethyst, rubies and diamonds.

"It was perfect for me. I felt they made it for me. It's very romantic," Alessandra said.
