Former Friends star Jennifer Aniston published the blog, For The Record, on the Huffington Post on Tuesday (July 12), writing how sick she was of being harassed by photographers and tabloid reporters.
"For the record, I am not pregnant."
"What I am is fed up.
"I'm fed up with the sport-like scrutiny and body shaming that occurs daily under the guise of 'journalism', the 'First Amendment' and 'celebrity news'.
"The objectification and scrutiny we put women through is absurd and disturbing... we define a woman's value based on her marital and maternal status"."
According to AFP via AsiaOne, Melissa McCarthy, Jason Bateman and Olivia Wilde were among the A-Listers who showed their support.
Said McCarthy: "Everybody needs to stop tearing down women."
Anniston's husband also showed his support by posting a black-and-white image of his wife with the hashtag #wcw for "Woman Crush Wednesday". He linked to her letter and wrote: "Here's just one reason why."
The blog post has garnered over 27,000 likes on Facebook.
However, British TV presenter and journalist Piers Morgan, who is editor-at-large of the United States edition of Britain's Daily Mail newspaper, published a counter-essay titled "My dear Jennifer, if you're so fed up with having your body judged, stop trying to make it look so Photoshop-perfect on magazine covers".
"There's another reason why the media objectify and scrutinise famous women, and why little girls get confused about beauty and body image," he wrote.
"It's this: Female stars like Jennifer Aniston deliberately perpetuate the myth of 'perfection' by posing for endless magazine covers which have been airbrushed so much that in some cases the celebrity is virtually unrecognisable."
