NEW YORK (AP) _ Sandra Bullock has declared the year of the thong.

Inspired by a trip to Brazil, the actress has decided ``just once in my life, even if it's for one day, I am going to stand on the front of my boat in a thong.''

Bullock has been eating better and exercising since January. Eight weeks ago, she started a regime called the Zone.

``It's just the basic principle of balanced eating,'' said the reformed junk-food junkie. ``I've lost 13 pounds, and I've taken 3 1/2 inches off my butt,'' Bullock told InStyle magazine.
