Alessandra Ambrosio in a White Bikini | Pictures

Alessandra Ambrosio kept busy yesterday with a bikini session in Malibu and an afternoon stop at Mr. Bones Pumpkin Patch in West Hollywood — see all the celebrities getting into the Halloween spirit! The whole family — Alessandra, her fiancé, Jamie Mazur, and their kids, Anja and baby Noah Mazur — joined in the hunt to find the perfect pumpkin. Jamie did most of the heavy lifting while Alessandra carried Noah.

At the beach, Alessandra changed into a white bikini for a game of volleyball. She gave us a sneak peek of the fit frame that we'll see more of when this year's Victoria's Secret Holiday Fashion Show airs on Dec. 4. She'll reunite with her fellow Angels Miranda Kerr and Candice Swanepoel, as well as musical guests Justin Bieber, Rihanna, and Bruno Mars.
