Tennis star Anna Kournikova has defended her dramatic weightloss, insisting she isn't suffering from an eating disorder. Since leaving the Women's Tennis Association circuit because of a back injury, the Russian pin-up has lost the voluptuous figure which once graced magazine covers worldwide. The 25-year-old beauty says her loss of bulk is down to her lack of tennis and says she is not starving herself. She says, "I'm naturally long, lean, and lanky. When I was playing tennis on the professional circuit, my body completely changed. "For nearly 15 years, I spent six hours a day on the court. "Now, almost three years have passed, and my body has changed again."
