Justin Bieber has hit back at his critics by posting a series of topless pictures of himself on Instagram.
The Baby singer has recently come under fire after writing a controversial message in the guestbook of the Anne Frank House in Amsterdam, where he questioned whether the Holocaust victim would have been a fan of his work.
Biebs wrote: "Truly inspiring to be able to come here. Anne was a great girl. Hopefully she would have been a Belieber."

After receiving a negative response for his comments, the museum leapt to the defence of JB, stating in a Facebook post: "The Anne Frank House was pleased to welcome Justin Bieber to the Anne Frank House last Friday.
"We think it is very positive that he took the time and effort to visit our museum. He was very interested in the story of Anne Frank and stayed for over an hour."
They added: "We hope that his visit will inspire his fans to learn more about her life and hopefully read the diary."

Justin himself has now appeared to mock his critics by posting snaps of himself working out at the gym, accompanying a close-up pic of his bod with the caption: "Uh oh @justinbieber is losing it taking shirtless pics in the mirror" -funny people."
He then added a second image of his toned torso, this time with [uuid=496649a7-6170-493f-a94e-3ca3adbb42cf]his new haircut[/uuid] clearly visible, and writing: "Breaking news worldwide @justinbieber just posted 2 shirtless pictures he must be going crazy" -funny people #forthefansanyways #dontbecreepin :p."
The 19-year old is yet to directly comment on his message in the Anne Frank House guestbook.

Meanwhile in other Bieber news, The Sun has claimed the Boyfriend hitmaker is looking for a home in Dubai ahead of his gigs on May 4 - 5 in the country.

A source told the newspaper: "He was going to stay in a hotel but is now looking at houses with a view to a longer-term stay. Justin will have to behave, though."
