Hollywood actress Catherine Zeta Jones has rejected rumours that she is suffering from anorexia.

The Entrapment star was speaking to People magazine at the Savannah film festival, where her husband Michael Douglas was given a lifetime achievement award.

Jones said she and her husband were amazed when they first heard about speculation that she was suffering from the eating disorder. The 38-year-old actress said a change in her diet had helped her lose weight and maintain her curvy figure, but dismissed reports that she was suffering from the illness.

“Michael was laughing at me. He told me what [people had] said – that stories say I’m anorexic. Do I look anorexic? How could I ever, ever be anorexic?,” she told the magazine.

The actress added that she used to crave bread in the past but was now working on “not chomping down what I usually chomp down”.

Later in the evening, her 63-year-old husband cracked up the audience at the awards show with jokes about the lifetime achievement prize he received and his age.

Speaking at the show the Wall Street star said: “As far as a lifetime achievement award goes, you always think, ‘Have they talked to your doctor?’”

The actor added that the couple’s two children were too young to know about their father’s achievements on the screen.

“Dylan is seven and Carys is four. I don’t have a movie that they can see. So up until tonight, they knew mommy is an actress and daddy makes pancakes. So thank you. Now they know what their father does,” he joked during his acceptance speech.
