I Felt Crazy Leder made his name as a photographer with Jacques, a magazine he and Danielle Hettara, then his wife and a former model, began publishing in 2009.
He was soon asked to shoot videos for brands like Adidas and Louis Vuitton.
Palmers agent emailed Leder in May 2011.
But Palmer and Ratajkowski used to be friends, although they hadnt shared their stories about Leder with each other until recently.
