Actress Kate Hudson has made a legal complaint against five publications over photographs she says wrongly suggested she had an eating disorder.
Ms Hudson is the daughter of Hollywood actress Goldie Hawn
The daughter of Hollywood star Goldie Hawn has instructed London law firm Schillings to act on her behalf.
The images gave a "seriously false and misleading impression", it said.
Letters have been sent to the Daily Mail newspaper, the National Enquirer, Heat, Closer and Star magazine, Schillings told the BBC.
Emap, publisher of the magazines Heat and Closer, confirmed they were in receipt of a letter from Schillings.
"We will make a response in due course," a spokeswoman said.
Schillings said an analysis of how the photographs came to be taken, sold and published will form a key aspect of its case.
The published images circulated widely in September and October 2005, it said.
The firm added the images were "used to accompany and illustrate articles which suggested that Ms Hudson had an eating disorder that was so grave and serious that she was wasting away to the extreme concern of her mother and family and although not stated, of commercial and artistic concern to those who might cast her in movies and choose to use her image to endorse products".
Almost Famous star Ms Hudson's weight and diet was of a healthy nature," both at the time of the images being taken and at present," it added.
