Singing sensation Jessica Simpson has denied she is suffering from anorexia nervosa and insists people from Texas don't get eating disorders.

The 25-year-old credits her strict Southern upbringing with giving her a love of food and is convinced her love for herself will never outshine her love of eating.

She says, "I'm not anorexic. I'm from Texas.

"Are there people from Texas who are anorexic? I've never heard of one and that includes me."
