Alessandra Ambrosio is serving up a little sex on the beach ... looking stunning as ever during a game of beach volleyball.
We got pics and video of the retired Victoria's Secret supermodel putting her amazing curves to work, having fun in the sun over the weekend at a beach in Los Angeles. Mother nature gets an assist on this one for turning up the heat so Alessandra could turn heads in a skimpy black bikini.
The mom of 2 is about to celebrate her 38th birthday ... and she's looking fine as hell!
