Counting Crows star ADAM DURITZ has stunned fans after losing 60 pounds (27.2 kilograms) on a protein cookie diet. The Mr. Jones singer, who dated Courteney Cox and Jennifer Aniston in his heyday, ballooned in recent years but decided to get in shape for a tour - and so took a pal's advice and got fit. His new regime includes protein cookies, one balanced meal a day and a strict exercise regimen. A pal says, "He feels great."
