GUESS has released new photos from a campaign for its Spring 2017 underwear line. In the sexy images, Joe Jonas strips down to underwear to model the brand's first ever men's underwear line, "Hero".

Joe looks blazing hot as he shows off his toned abs and chiseled body. The DNCE frontman also strikes steamy poses with model Charlotte McKinney, letting the model touch his chest from the back. Another picture shows Joe holding Charlotte's jeans while the model touches his hair.

Joe is the first man ever to star in GUESS underwear campaign. He was chosen by Paul Marciano, GUESS' Chief Creative Officer & Executive Chairman of the board, who said, "I am very excited to have Joe Jonas on-board as the newest face of GUESS. Joe is a cool and charismatic young man who embodies all of the characteristics of GUESS' DNA - sexy, young and adventurous."

GUESS underwear campaign is Joe's first ever underwear photo shoot. He admitted he was nervous during the photo shoot, saying, "It can be a weird thing to be sitting there in your underwear being photographed, but overall I had a blast." He also revealed that he dieted and did a lot of boxing and cardio with his trainer before the photo shoot to get a perfect body.

This is not the first time to see a Jonas in an underwear campaign. In 2014, Jonas' brother Nick Jonas modeled underwear for Calvin Klein. His pictorials made quite a buzz for his provocative pose as he grabbed his crotch while looking at the camera.
