Demi Moore In A Teeny Bikini (VIDEO)

Demi Moore showed off her toned body in a teeny bikini with husband Ashton Kutcher in St. Barts New Year's weekend.

Over the summer Demi, 48, took photos of herself in a bikini looking into a bathroom mirror and posted them on Twitter - a shoot that Lisa Rinna, a 19-year-old male friend, and Ashton's purported mistress soon reenacted. Ashton once tweeted a photo of Demi's bikini-clad bottom.
