Alessandra Ambrosio hit the beach in a two-piece Saturday in Hawaii. She's off on a family vacation with her fiancé Jamie Mazur and their young daughter, Anja. The afternoon on the sand included a bit of surfing for Alessandra before she retired to a deck chair with Anja. It was apparently great fun for Alessandra, who tweeted, "surfing in Waikiki is just amazing!" We last saw Alessandra Ambrosio in her bikini earlier this Summer, in May, during a Memorial Day stroll in Malibu with her family and little dog. There's been lots of work for Alessandra since then. She hit the CFDA Awards in June and then went to her home country of Brazil to shoot ads for Colcci alongside Ashton Kutcher. Alessandra is resting up now, though, writing yesterday on Twitter, "Hawaii, sunset, spa — so relaxing!"
