Joe Jonas and Guess have unveiled a new underwear campaign that's a must for, well, any fan of seeing the DNCE frontman with his clothes off. The clothing brand and the musician both unveiled the steamy new photos on Wednesday (January 11), proving that Joe, like his brother Nick Jonas, isn't afraid to show of his gym results in a photo or two.

The photos were shot by Yu Tsai, who also happened to shoot Nick's infamously racy Flaunt magazine spread back in 2014. They find Nick posing with a fan (literally, it's an unplugged fan) and with model and Joe's "Body Moves" video costar Charlotte McKinney. An oiled-up Joe models a variety of boxer briefs, t-shirts and jeans from a collection that launches in February. Jonas also has the honor of being the brand's first male star of an undies campaign.

"I am very excited to have Joe Jonas on board as the newest face of Guess," Guess Chief Creative Officer Paul Marciano said in a statement. "Joe is a cool and charismatic young man who embodies all of the characteristics of Guess’s DNA — sexy, young and adventurous."
