Keira Knightley, the Pirates of the Caribbean star, has taken a libel action over a newspaper story that suggested she was losing too much weight and could be anorexic.
The 21-year-old actress believes the Daily Mail article suggested she had "dishonestly sought to mislead the public" over whethershe has an eating disorder.
In the article, earlier this month, Rosalind Ponomarenko-Jones, who lost her daughter Sophie Mazurek to anorexia, discussed the impact of celebrities such as Knightley on vulnerable young women.
A photograph of her daughter, who was 19 when she died last month, was printed next to one of Knightley in a bikini. The article described the actress as "skinny" and said that "for ordinary young girls, attempting to emulate this image is often dangerous".
Lawyer Simon Smith said: "We wish to make clear that Ms Knightley has the deepest sympathy for the girl's family. However, Ms Knightley has publicly denied suggestions that she might be anorexic or have a similar eating disorder ... and will challenge the suggestion that she is ... to blame for the tragic death of the teenage girl by setting a bad example."
The case is due to go to jury trial at the High Court in London this year.
