Elle MacPherson Kayaking in Bikini in Sydney Pictures

Elle Macpherson was out and about today in a bikini as she continued her vacation in Sydney. The supermodel and lingerie designer showed off her fit frame in a two-piece as she stepped out into the Aussie Summer for yet another afternoon in the sunlight. Elle is back in her native country with her sons and her parents for the holidays, and has been staying active during her downtime, kayaking with her boys and splashing in the water. Elle's trip home caps off what was a busy 2011 for the model-turned-entrepreneur. Her Elle Intimates' bridal line launched over the Summer, and she also signed on to host Fashion Star — Nicole Richie and Jessica Simpson's new reality series — earlier this year.
