Demi Moore, 59, flaunts her age-defying figure in a bikini while enjoying a Greek getaway on a yacht

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

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

She placed her chiseled stomach forward and center of the look, flaunting her toned obliques with low bottoms that she pinned at her hips.

Demi eschewed jewelry and appeared fresh-faced and makeup-free beneath her dark shades, which have been a fashion staple of hers for years.

She has sometimes been seen carrying her teacup-sized Chihuahua, which she calls Pilaf. She cradled the puppy in her arms and was still holding him as she released him.

Throughout the day, she also used her iPhone, chatted to a friend who wore a white bikini, and stretched out with a book.

And the Ghost actress took precautions, making sure to wear protective sunscreen while tanning under the bright sunlight.
