Elle Macpherson has no problem stripping down to a bikini at age 51 -- and why not?! The former super model still looks picture perfect in next to nothing!
Macpherson sported a black bikini on a yacht in Porto Cervo, Italy this weekend.
She dipped her long lean body into the water with her cowgirl hat still in place.
She's so serious about sun protection that she swims with a hat and shades!
She did take the time to shimmy out of her swim skirt.
When she wasn't swimming, she was staying hydrated with a cool drink on the upper deck.
Her long turquoise necklace almost covered more skin than her bikini!
Macpherson has learned to capitalize on her ability to sustain her enviable physique -- she has released a line of energizing protein powders!
