What better way is there to show critics what you think of them than do exactly the thing they are criticising you for all over again? Justin Bieber took to Instagram to send a firm message out to his critics via his very buff chest For some crazy reason, people aren't fans of Bieber's shirtless pictures. We can't think of one reason why. Seriously. Our day definitely brightened at the sight of Beibs pecs... The 19-year-old singer posted his first snap with the caption, "'Uh oh @justinbieber is losing it taking shirtless pics in the mirror' - funny people." Uh-oh. We think someone's having a tanny tantrum! Biebs didn't stop with one pic. He treated us to a second captioned at first with, "'Breaking news @justinbieber posts two shirtless pictures in a day could he be anymore full of himself' - silly people." He quickly deleting that caption and replaced it with, "'Breaking news worldwide @justinbieber just posted 2 shirtless pictures he must be going crazy' - funny people #forthefansanyways #dontbecreepin :p” Yeah, critics! Bieber’s pecs are for the fans ANYWAYS so just deal with it.
