Justin Bieber Shrugs Off Anne Frank Controversy With Topless Twitter Photos

Justin Bieber has been at the centre of controversy (again) after his comments about Anne Frank, but the star has hit back at critics who suggest he is losing it - with some topless snaps, obviously.

Justin posted two photos of himself sans shirt following a gym session, writing: "Uh oh @justinbieber is losing it taking shirtless pics in the mirror" -funny people."

The other caption read: "Breaking news worldwide @justinbieber just posted 2 shirtless pictures he must be going crazy" -funny people #forthefansanyways #dontbecreepin :p."

However, the singer is yet to comment directly on the furore that erupted after he wrote in a guest book at the Anne Frank House that he hoped the Holocaust victim would have been a fan of his.
