Hollywood actress Jennifer Lawrence has spoken up about an incident early on in her career, when she was forced to take part in a ‘naked line-up’.

Her revelations come as Hollywood is blown open by the Harvey Weinstein scandal, reports The Telegraph.

She spoke about the ‘degrading and humiliating’ experience at Elle’s Women in Hollywood event on Monday night, telling the audience she was told to lose 15 pounds by film producers.

Ms Lawrence claimed another actress was fired from the role for not dropping the weight quick enough.

The actor said that then, she was made to take part in a ‘naked line-up’ with slimmer women, as ‘inspiration’ for her diet.

She said: ‘During this time a female producer had me do a nude line-up with about five women who were much, much, thinner than me.

‘We are stood side-by-side with only tape on covering our privates. After that degrading and humiliating line-up, the female producer told me I should use the naked photos of myself as inspiration for my diet.’

The situation worsened when she told a male producer that she would not lose the weight.

He said he ‘didn’t know why everyone thought [she] was so fat’, and that he thought she was ‘perfectly f---ble’.

The actor said she felt she had to be treated that way or her career would not progress.

She said:  ‘I’m still learning that I don’t have to smile when a man makes me uncomfortable.’

Ms Lawrence also claimed the director of the film asked her to star in a pornography movie, as the main character, and said other, more inappropriate things to her when she was a young star.
