Elle Macpherson and more flaunt their bikini bods

Hot mama! Elle Macpherson, 51, flaunted her super toned bod on vacation in St. Tropez, and it's safe to say she hasn't aged a day.

The Aussie supermodel, known internationally as "The Body," lived up to her flattering nickname in a black three-quarter sleeved crop top, bikini bottoms and a baseball cap while at sea -- not to mention, her envy-worthy beach hair.

The mother of two isn't the only one getting some vitamin D. Actress Emily Ratajkowski, 24, has also been posting snaps from her Italian vacay, sporting various combinations of sexy swimwear, including a red-hot bikini and an ab-bearing one-piece.

See the two stunners and more in the slideshow above.
