NICOLE Richie has spoken out to debunk claims she had anorexia. The reality TV star insists accusations she suffered with an eating disorder were completely untrue. It was a little unfair to say someone has an eating disorder when they dont, the 28-year-old mother of two told Marie Claire. Its extremely insulting and irresponsible. An eating disorder is serious and its a disease. The National Enquirer recently claimed that Richie has vowed to boost the health of two of her closest friends - actress Mischa Barton and celeb stylist Rachel Zoe. SS Nicole has battled weight issues, but finally figured out how to balance her life, and is determined to lead Mischa and Rachel to a happier and healthier lifestyle, an insider said. Mischa has been down lately because her career has been in limbo, and rather than returning to the party scene, she has turned to food. Mischas career has been foundering. Her last series The Beautiful Life was cancelled - and shes been eating everything in sight for solace. Tiny Rachel is at the other end of the spectrum. She works so hard dressing her A-list actress clients that she literally forgets to eat. Nicole has stepped in and had one-on-one interventions with Mischa and Rachel. Shes counselled both on a healthier way of life and how to incorporate nutritious organic food into the stress-filled schedule of a celebrity. Nicole overcame her body-image and substance-abuse problems and she wants to help her friends Mischa and Rachel have the same success. SS
