Emily Blunt is not cool with the "mummy cult."
The 33-year-old actress is currently promoting her highly anticipated film, The Girl on the Train, and reflected on her character Rachel's complex relationship with another woman in the film, Megan (Haley Bennett), as well as Rachel's struggle with fertility treatment.
"I think there is a huge societal pressure on women when it comes to motherhood, this sort of mummy cult that goes on," Blunt, who is a mother to two daughters with husband John Krasinski, tells The Guardian. "And I think it sort of makes women feel that they have to be a bit defensive about the choices that they make, whether they want to be a mother, whether they don't, whether they want to breastfeed, whether they don't. I could go on and on."
"In the domestic world, I think it's when women can be a bit cruel about each other, more so than any other environment," she adds. "And I think this film really captures that."
Blunt looked gorgeous at the film's London premiere on Tuesday, when she sported a colorful Alexander McQueen long-sleeve gown.
The actress also addressed critics who claim she's too pretty for the role of Rachel Watson, as well as shared her thoughts on what it's like adapting such a popular novel as Paula Hawkins' bestseller.
"I think people should see the film before they decide if they think I look pretty or not," Blunt declared. "I think any time a character or certainly a book is beloved, you’re going to be met with some resistance to whoever is cast or whoever is doing it. But at the same time, all I could think of is that it's going to have to be my version of her whether people like it or not."
"Once we started filming, it didn't enter my mind that much," she added.
Of course, the British actress isn't the only celeb speaking out against mom shaming. In July, model Chrissy Teigen passionately defended Kristin Cavallari when some Instagram users criticized the former reality star for posting an Instagram photo of her two sons -- 4-year-old Camden and 2-year-old Jaxon -- apparently appearing too skinny.
"I will never know why parents criticize others so harshly, knowing they'd go insane if they were on the receiving end ALLTHETIME," Teigen tweeted, who herself has been targeted by socia media critics when it comes to her daughter, Luna, with husband John Legend. "NO parent out there thinks they're perfect. I loathe these sh**head commenters. Who would want to make someone feel horrible for fun?"
