The Perils of Being a Size 0

TMZ reports that Nicole Richie collapsed just before 2AM Sunday morning, while partying at Hyde nightclub in Hollywood (her publicist denies it, of course).  This is only days after Richie entered a residential treatment facility for her weight.

Richie has gone from healthy to scary:

The transformation seemed to begin when Richie hooked up with stylist, Rachel Zoe.  Zoe transformed Richie's look, and she began wearing a chic, boho style at the same time as she began shrinking in size.  Some rumors suggest Zoe is partly responsible for the weight loss, and that extreme measures have been in play.  It has been alleged that Zoe offers her clients diet drugs to help them stay slim.  While these allegations seem far-fetched, she's a stylist not a pusher, (moreover Zoe denies them), they speak to the difficulty of achieving weight loss without taking extreme measures.
