Thanks to her incredible figure, Elle Macpherson long ago became known by the nickname “The Body.”
Now 47, the legendary supermodel shows she’s still sexy after all these years, frolicking on the beach in Malibu wearing nothing more than her signature triangle bikini for a PEOPLE photo shoot (her first swimsuit session in six years). Watch video of the model in action on the set of her shoot below.
While the mother of two says her killer curves are the product of a clean diet, daily exercise and good genes – and not the surgeon’s knife – she admits that even she is not immune to the body blahs.
“I do get jitters,” says the Australian model, who turns 48 on March 29. “I was comfortable [at the shoot]. But I had to get my self-conscious ‘maybe I don’t look my best’ head out of the way and go with, ‘Let’s celebrate where I’m at.’ ”
