>

Demi Moore showed off her incredible figure over the weekend as she enjoyed a sun-filled day out on a yacht with friends in Greece.

The 59-year-old mother-of-three smiled as she cruised the sea in a teeny hot pink string bikini that bared her svelte frame.

The brunette bombshell put on a skimpy display and wore her long, textured locks loose while shielding her eyes in black aviator frames.

The actress’ perky cleavage was front and center in the low-cut top, which had spaghetti straps and tied in the back.

She put her chiseled abdomen front and center in the look, baring her toned obliques with low-rise bottoms that she fastened on her hips. 

Demi skipped jewelry and appeared to be fresh-faced and makeup-free underneath her dark sunglasses, which have been a fashion staple of hers for years.

At times she was seen carrying her teacup-sized chihuahua, who she calls Pilaf. She cradled the pup in her arms, still keeping it close when she let it free.

Throughout the day she also used her iPhone, chatted up a gal pal who was clad in a white bikini, and stretched out with a book.

And the Ghost actress took precaution, making sure to sport protective sunscreen while catching a tan under the beaming sunlight.
