The 'Friends' star penned a lengthy piece for The Huffington Post where she wrote about how "fed up" she is of constant rumours she is pregnant", the "shocking lengths" photographers go to to take her picture, and the "objectification and scrutiny" of women.

And now her spouse, 44, has chosen her as his "woman crush Wednesday" for speaking out.

Alongside a black and white picture of the 47-year-old actress and a link to her article, he wrote on Instagram: "#wcw Here's just one reason why. #Gogirl.(sic)"

The 'Leftovers' actor isn't the only person to speak out and support the 'Cake' star.

Melissa McCarthy said she agreed "one hundred thousand billion percent" with Jennifer.

She told 'Entertainment Tonight': "Everybody needs to stop tearing down women.

"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.'

"It's a ridiculous thing. I just hope it gets to the point where it's embarrassing for people to have such a shallow thought."

Cheryl Fernandez-Versini took to Twitter to praise the actress for her stance.

Sharing a link to the article, she wrote: "Just when I thought I couldn't love her any more (sic)"

'Vinyl' actress Olivia Wilde also agreed with what she had to say in the essay.

She tweeted: "True words by Jennifer Aniston: "We use celebrity 'news' to perpetuate this dehumanizing view of females."(sic)"

Model Rosie Huntington-Whiteley described the piece as a "must read", a sentiment echoed by 'Twilight' actress Nikki Reed.

Nikki posted: "Wowza! Everyone should take a second to read this incredibly powerful op-ed written by Jennifer Aniston for Huffington Post. Beautiful, eloquent, and a true dose of kickass."

In her essay, Jennifer insisted she wasn't only speaking out for herself.

She wrote: "The objectification and scrutiny we put women through is absurd and disturbing. The way I am portrayed by the media is simply a reflection of how we see and portray women in general, measured against some warped standard of beauty.

"Sometimes cultural standards just need a different perspective so we can see them for what they really are - a collective acceptance ... a subconscious agreement. We are in charge of our agreement. Little girls everywhere are absorbing our agreement, passive or otherwise."
