The 'Simple Life' star Nicole Richie has admitted she is too thin and has revealed she wants to take care of her health.
She said to Vanity Fair magazine:
I know I'm too thin right now, so I wouldn't want any young girl looking at me and saying, 'That's what I want to look like'. 
She went on to say:
I started seeing a nutritionist and a doctor I get weighed once a week, but I don't ask. Numbers aren't going to mean anything to me.
