Emily Ratajkowski attacks a photographer who is putting all of her nudes in a book without her permission.

Model and actress Emily Ratajkowski has hit out at a photographer who has released a series nude images of her without approval, saying they are “an example of exactly the opposite of what I stand for.”

Tweeting about the Polaroids on Thursday morning, which are included in a book by photographer Jonathan Leder, Ratajkowski began, “I’ve been resisting speaking publicly on the recently released photos by Jonathan Leder to avoid giving him publicity. But I’ve had enough.

“The book and the images within them are a violation,” the 25-year-old continued.

Deceptively titled Leder/Ratajkowski, the book is a collection of both clothed and nude images Leder took of Ratajkowski in upstate New York back in 2012 for a magazine shoot. The outtakes, however, now make up the book, which Ratajkowski says, she never agreed to.

"5 out of the now 100s of released photos were used for what they were intended: an artful magazine shoot back in 2012," Ratajkowski's tweets continued.

"These photos being used w/out my permission is an example of exactly the opposite of what I stand for: women choosing when and how they want to share their sexuality and bodies," she wrote finally.

Agreeing to a shoot destined for a magazine is one thing. But having a photographer stash away the outtakes for four years only to turn them into a book with your name in the title and release them when you're at the height of your fame (without asking for your permission) in the revised context - not cool at all.

It's hardly the first time the Entourage star has called out sexism when she sees it.

In February, Ratajkowski penned an essay for Lena Dunham's Lenny Letter titled 'Baby Woman' and spoke about growing up in a sexualised world and learning to be the master of your own liberation.

"I refuse to live in this world of shame and silent apologies. Life cannot be dictated by the perceptions of others, and I wish the world had made it clear to me that people's reactions to my sexuality were not my problems, they were theirs," the Blurred Lines star wrote.

And in March she made headlines once more when she posted a topless selfie with reality television queen, Kim Kardashian West, both of them giving viewers the middle finger.

Neither Leder or the book's publisher, Imperial, have commented on Ratajkowski's claims as yet.
