She like big butts and she can not lie...

Vanity Wonder, 30, is the women with this unreal butt:

She didn't get it by doing squats, she did it by injecting some weird substances into her rear end. 

In a new book called Shot Girls, written by Vanity herself, readers can follow her experiences of seeking out and having the injections, and how she became an assistant to a black market practitioner, who treated women from 17 to 70. 

Vanity told The Daily Mail she wrote the book because, 'So many people tell so many lies about the women who get injections,' she explained. 'It's such a secretive thing. I decided to tell people rather than letting them just guess.' 

Vanity says her butt is made by grade A silicone. As long as she can booty drop, it's fine with me.
