This Brazilian woman left her competitors in her “rear” view.

Suzy Cortez was crowned Miss BumBum 2015 Monday following a backside battle with 15 other “butt”-acious babes.

“I’ve been preparing myself for the past four months,” she told The Daily Mail shortly after her win. “I dedicated myself completely.”

Cortez, who is from Distrito Federal, dedicated hours to a “rigorous training” program, as well as dieting, to get the perfect rump.

The group of competitors, which started with more than 500 women, had to prove that they didn’t have any implants or surgeries to enhance their derrieres after the 2014 runner-up almost died from a botched procedure.
