Someone is reading what the press says about him. Justin Bieber, whose image has been taking a regular beating lately, the latest over an Anne Frank gaffe, mocked the media by posting defiant shirtless photos of himself with hilarious captions.

The Biebs is in a gym and in seriously good shape, as his washboard abs indicate. However, he is also looking yard hard, with lots of tattoos sprinkled all over his torso and arms, while his posture is sorely lacking. Stand up straight, Biebs! Scooter, quick. Balance a book on his head like they do to teach girls posture in finishing school. Who cares if it messes up that famous coif? He needs to stand up straight.

One photo was accompanied by this snide comment: "Breaking news worldwide@justinbieber just posted 2 shirtless pictures he must be going crazy - funny people #forthefansanyways#dontbecreepin :p"

The second nodded to his "issues" as well. He posted:"Uh oh @justinbieber is losing it taking shirtless pics in the mirror - funny people."

He's having fun and bringing some levity to a situation -- the paparazzi, media spin and negative press -- that brings him many headaches. At least he has a sense of humor about it.
