The skinny singer-turned-fashion designer Victoria Beckham is the latest figurehead to clamp down on too-thin catwalk stars - even though she sports a tiny figure herself.
When Beckham launches her new range of denim, she promises it will be modelled by curvier women.
A source tells British newspaper The Sun, "Victoria wants to give out a positive image that you don't have to be ultra skinny to look good. Many of the models on the catwalk make young girls feel insecure about their own bodies."
Although the star herself believes many models are naturally thin, she says, "I know quite a few models and they do eat. They are just naturally thin girls."
