Shawn Mendes isn’t holding back anymore. The “In My Blood” singer posted some new photos to social media on Saturday.

“@CalvinKlein #MyCalvins. Campaign coming this week,” Mendes said as he posted the photos. In one, he’s sitting back on a chair with his legs spread and surrounded by musical equipment. He’s clad in only a pair of black Calvin Klein boxer briefs. In the other photo, Mendes is leaning back on a kitchen counter, showing off a pair of white Calvins.
