He said: ''I don't know if I'm a sex symbol or what that even means. But if I am one, fine by me!''
The Baby singer landed a contract modelling underwear for the brand after posting a picture of himself on Instagram of himself in his boxer shorts last March.
He added to Us Weekly magazine: ''Modelling for Calvin Klein was always my dream. And it got their attention.''
The singer worked out five times a week with his personal trainer to prepare for the photoshoot and even lifted weights during it, and he hopes Mark is a fan of his work.
He said:''I hope he reacts positively to my ads.''
Meanwhile, the Canadian star, who is rumoured to be dating Hailey Baldwin following his split from long-term girlfriend Selena Gomez last year, insists he is enjoying being single.
He said: ''Single life is great. It's given me time to focus on myself.''
