Alessandra Ambrosio wore a bra and her Victoria's Secret Angel wings during a shoot in Miami yesterday. The brand's keeping Alessandra busy — at the end of 2012, Alessandra Ambrosio was in a bikini for a shoot in St. Barts. She found time to tweet between poses, writing, "Working hard today!" Yesterday, she was happy to be "back to the warm weather" when she arrived in Florida. Alessandra's been hanging out at home in California, where it's been cold, with her two kids, Anja and Noah, and her fiancé, Jamie Mazur. Earlier this week, Alessandra was layered up to take a walk in cold Santa Monica with Anja.
