Olivia Wilde and Anna Paquin also had Aniston's back.
Chrissy Teigen again found herself in a Twitter feud with Piers Morgan on Wednesday, after he spoke out about Jennifer Aniston's powerful new op-ed, in which she addresses the numerous pregnancy rumors and explains how the "stalking and objectification" she has endured by the media is harmful to women.
"I resent being made to feel 'less than' because my body is changing and/or I had a burger for lunch and was photographed from a weird angle and therefore deemed one of two things: 'pregnant' or 'fat,'" the actress writes. "We use celebrity 'news' to perpetuate this dehumanizing view of females, focused solely on one's physical appearance, which tabloids turn into a sporting event of speculation."
In an editorial piece for the Daily Mail, Morgan says he finds Aniston's comments to be hypocritical. "There’s another reason why the media objectify and scrutinise famous women, and why little girls get confused about beauty and body image," he explains. "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 unrecognizable."
He adds, "Once you put your body up for lucrative personal gain, I’m afraid you have to accept a level of scrutiny and debate that comes with it."

Morgan writes that he anticipated "the furious vitriol" from the "world's feminists," and Teigen was one of the first to speak out against his point of view. "Piers Morgan, saw your piece on Jennifer Aniston. Why do you ALWAYS take the road of being the piece of sh** a**hole?" she tweeted on Wednesday morning. "Particularly with women and people of color. Tell me it's just for clicks?? Please tell me you aren't TRULY this vile."
The supermodel continued: "I think you aren't this bad and have simply sold your soul for clicks. Which is even sadder than actually believing you're garbage."

Morgan replied: "You didn't actually read it did you...? Try doing that before throwing another diva tantrum."
Teigen fired back: "Unfortunately, I read it. I'm not so much a diva as I am a person who slows down at car crashes, apparently."

After a brief back-and-forth, Morgan announced on Twitter that John Legend's wife had blocked him. "It was fun @chrissyteigen -- come back when you can handle adult debate," he wrote. "I fear Ms. Teigen is a very spoiled little madam used to spewing bile without consequence and getting her own way."
The British TV personality then quipped: "Might have to do my next column on @chrissyteigen -- just to REALLY annoy her."

While Teigen was hashing it out with Morgan, other celebrities were also coming forward in support of Aniston.
"True words by Jennifer Aniston: 'We use celebrity 'news' to perpetuate this dehumanizing view of females,'" Olivia Wilde wrote, quoting the actress' Huffington Post piece.
"Please listen to the words of #JenniferAniston She is speaking from her heart and mind. We need to listen for all of us," Maria Shriver insisted.
LeAnn Rimes Cibrian also quoted the Friends star, tweeting: "'We get to decide how much we buy into what’s being served up.' -Jennifer Aniston #empoweringwomen."

"An important article by Jennifer Aniston," Anna Paquin posted. "I think the point that is being missed is that #JenniferAniston having a privileged life doesn't mean she doesn't get to react to this crap."
ET caught up with Melissa McCarthy at the New York City premiere of Ghostbusters, and she too had the 47-year-old actress' back. “Everybody needs to stop tearing down women,” she declared. "It's always about the way we look -- saying, ‘He's very interesting,’ ‘He’s a good writer,’ ‘She's looking older than she was last time we saw her.’"
