Simple Life' star Nicole Richie has sparked health concerns after collapsing at a Hollywood nightclub in the early hours of yesterday morning (29.10.06).

'The skinny - who announced on Friday (27.10.06) that she was seeking medical treatment for her dramatic weight loss - passed out at 2am at hip night spot Hyde.

Last month, Richie slammed reports she's checked herself into an eating disorder rehabilitation clinic, insisting she is "happy and healthy".

The skinny star posted a comment on her MySpace.com blog site denying the rumors, which surfaced that 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.

Now source told TMZ.com: "An employee approached Nicole and her
friends and said he was calling 911. They told him not to make the call and
that they would take her to hospital themselves. Then they carried her out
of the back door."
It is not yet known if Nicole, the 25-year-old adopted daughter of singer
Lionel Richie, made it to hospital.
A spokesman for Nicole confirmed she was in Hyde for approximately 20
minutes but has denied she collapsed.

Before she allegedly collapsed witnesses saw Nicole hanging out with actress
Lindsay Lohan.
At 6.45am yesterday Lindsay is said to have been spotted sitting in her car
by a man walking his dog on Sunset Boulevard, in Hollywood.
The 'Mean Girls' star was said to be talking on the phone and "freaking
out".
