Sometimes, life is hard -- we realized that most as we were looking for pictures of shirtless hotties all day. Just kidding! We love us some shirtless celebrity studs like Adam Levine, Justin Bieber and Chris Brown.

Sometimes when these guys are shirtless, we forget they have faces, names, songs, etc... All we can fixate our minds (and eyes) upon are those impeccable physiques.

If you want to be a pop star nowadays, you better be toned liked Carlos Pena of Big Time RushUsher, and Harry Styles of One Direction. If not, prepare to have the ladies swoon over someone else because it's all about the abs, biceps and pecs. And we have to give credit where credit is due, these guys pump iron and go through rigorous workouts just to keep the lady folk coming back for more.

Check out shirtless celebrity pictures below and give it up for these hotties of pop music!
