Freaky Friday star Lindsay Lohan has spoken out over reports that she suffers from anorexia.

According to Teen Hollywood, the 18-year-old actress has rubbished the claims by saying that her recent weight loss is simply a product of growing up and is not a result of any changes in diet.

She explained: "Even the doctor (I saw) today, he was like, 'Are you anorexic? Are you making yourself throw up? Are drugs involved?'

"And I was like, 'Are you saying this because you've read it in magazines? Because I don't!' People lose weight when they grow up; they lose their baby fat."

Lohan was also at pains to explain that she was growing up last year when there was speculation that her blossoming breasts were aided by implants.
