MOL Los Angeles - She’s never been one to bite her tongue. And Jennifer Lawrence, while admitting she loves her job, has condemned another Hollywood sticking point - her business’ obsession with weight.

Just a couple of months after she wrote an open letter on sexism in the industry, the 25-year-old Oscar winner has had her say on the aesthetics of acting, telling Grazia that an actress should be ‘judged on talent’ not looks.

The Hunger Games star became the highest paid actress in the world this year thanks to her lead role in the smash hit franchise and award season favourites with her favourite director David O. Russell, including latest project Joy. Jennifer may be riding high in Hollywood, but she has told Grazia she is still dismayed by many aspects of her profession. ‘I hate all the focus on weight and size that you have in our business,’ she has explained in a new interview. ‘I don’t think an actress needs to be skinny to be attractive and it sends the wrong message to young women. It’s important that, as actresses, we need to establish ourselves first and foremost for our talent and not for our physical appearance.’

Jennifer went onto discuss another issue close to her heart, fair pay. In October the star hit the headlines when she wrote an open letter on sexism in the film industry, saying she was ‘over trying to find the ‘adorable’ way to state her opinion.

She explained that she felt she had to act ‘on principle’. ‘I’m aware that movie stars earn too much money in relation to the rest of the world. But it’s the principle that is important. I can’t stand a lack of fairness. This has nothing to do with ingratitude - I love my job and I know how lucky I am to be able to live off my art,’ she pointed out.

‘But I also know that there has never been such a successful franchise with a woman in the lead role in Hollywood history. And if that encourages a rethinking of the studio bosses, or if my work has in any way helped to achieve equality for women in this business, then I will be very grateful to have done my part.’

Back in October Jennifer penned an essay for Lena Dunham’s feminist arts newsletter, Lenny Letter, which revealed her fury at discovering that she had been paid less than the ‘lucky people with d**ks’ in her 2013 film American Hustle.
