Latest: Socialite Nicole Richie has slammed reports she's checked herself into an eating disorder rehabilitation clinic, insisting she is "happy and healthy".

The skinny star has posted a comment on her MySpace.com blog site denying the rumours, which surfaced earlier this week.

Richie fumes, "Contrary to CNN's false accusations, I did not check myself into an eating disorder rehab. I do not have an eating disorder. Whoever has started this rumour is evil and mean but it's not true. "I am happy and healthy and living my life."

Her publicist Nicole Perna added, "Nicole has decided to undergo diagnostic treatment to determine why she's not been putting on weight. This is not treatment for an eating disorder."

Filming on the fifth season of Richie's reality TV show The Simple Life has been postponed while she undergoes the treatment.
