Shawn Mendes isn't holding much back in a pair of new photos -- featuring the "In My Blood" singer in just his underwear -- that he posted on social media Saturday (Feb. 16).
"@CalvinKlein #MyCalvins. Campaign coming this week," Mendes promised alongside the pictures. In one, he's sitting back in a chair with his legs spread, wearing a pair of black Calvin Klein boxer briefs, musical equipment by his side. In another, he's casually posing by a kitchen counter, sporting just a white pair of Calvins.
