Annoying Pop Star Habit: The endless amounts of topless and shirtless Instagram pictures that scream "COMPLIMENT ME."

Pop stars of the world, if you have never posted a topless or shirtless picture on Instagram, please step forward... not so fast, Justin Bieber and Rihanna.

Fans love when their idols post pictures of themselves scantily clad, and every once in a while, it's great. Part of a pop star's job is to stay in shape, so it's cool they occasionally show off their rock hard bodies, since they work so hard for them. Just please, we beg of you, practice this in moderation. If you have more half-naked pictures posted than fully-clothed ones, than you may have a problem in the vanity department.

Our newest slogan for pop stars: Just Say No to Half-Naked Instagramming.
