Justin Bieber's shirtless Instagram photos could have landed him a major endorsement deal.  

"Daily Mail" says the pop star recently took part in a photo shoot for Calvin Klein that's expected to go public later this year.  The report is leading to speculation that the singer is set to be brand's next coveted underwear model.  Bieber's people are not commenting.  Rumors about the possible collaboration started back in April when Justin traveled to New York City.  At the time, reality TV star Kendall Jenner was also linked to the rumored shoot.


Justin frequently posts pictures showing off his abs with the signature Calvin Klein label poking out from under his baggy pants.  The most recent of those pictures appeared on his Instagram page on Tuesday.
