Crystal Renn says being a plus-sized model was too pressurised.

The 25-year-old beauty has seen her weight fluctuate over the years and despite being very successful when she was at her heaviest, she admits the pressure became too much.

Crystal - who is now a US size six and UK 10 - said: ''I think that by placing a title on my head, which is 'plus-size,' and then the picture that these people have created in their mind about what plus-size actually is, I've basically failed you just with that. Because I couldn't possibly live up to that, and at this point in my life I would have to actually have another eating disorder to live up to that expectation.''

As well as her weight changing, Crystal recently dyed her hair platinum blonde and said she was ''excited'' by her transformation.

She recently revealed: ''People can't believe the transformation. I had black hair and now I have white hair.

''That's what's so exciting. I wanted to do something different. I wanted to show up as a different canvas at a shoot. It's a very extreme look but very beautiful. Though it's nothing conventional.''
