Justin Theroux is one proud husband.

The 44-year-old actor/screenwriter took to Instagram on Wednesday to show support for his wife, Jennifer Aniston, after she penned an empowering op-ed against body shaming and the judgment women feel for not being married or having children. Theroux shared a black-and-white photo of Aniston, 47, sitting on the floor of what appears to be a bowling alley, calling her his "woman crush Wednesday."

"Here's just one reason why," Theroux wrote, linking to Aniston's essay on The Huffington Post. "#Gogirl."

Aniston's open letter was in response to speculation that she was pregnant last month, after bikini pics of her while on vacation with Theroux in the Bahamas were published. Her rep quickly shut down the rumors, telling ET, "What you see is her having just enjoyed a delicious big lunch and her feeling safe on private property."

"Yes, I may become a mother some day, and since I'm laying it all out there, if I ever do, I will be the first to let you know," Aniston wrote in her essay published Tuesday. "But I'm not in pursuit of motherhood because I feel incomplete in some way, as our celebrity news culture would lead us all to believe."

"Here's where I come out on this topic: we are complete with or without a mate, with or without a child," she later added. "We get to decide for ourselves what is beautiful when it comes to our bodies. That decision is ours and ours alone."

Theroux isn't the only one supporting the former Friends actress' message. When ET caught up with Melissa McCarthy at Gildafest '16 in New York City on Tuesday, the Ghostbusters star said she agrees with Aniston "one hundred thousand billion percent."

"Everybody needs to stop tearing down women," McCarthy said. "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," she continued. "I just hope it gets to the point where it's embarrassing for people to have such a shallow thought."
