Justin Bieber has been criticised for an entry he wrote in a guest book at the Anne Frank House museum in Amsterdam, saying he hoped the Jewish teenager who died in a Nazi concentration camp "would have been a Belieber" - or fan of his - if history were different.
The singer's message triggered a flood of comments on the museum's Facebook page, with many criticising the 19-year-old Canadian pop star for writing something they perceive to be insensitive.
Museum spokeswoman Maatje Mostart confirmed Bieber visited on Friday evening. She said the museum was happy to have received the singer and did not see anything offensive in his remarks.
Anne Frank hid with her family in a small apartment above a warehouse during the Nazi occupation of the Second World War. Her family was caught and deported, and Anne died of typhus in Bergen-Belsen in 1945. The diary she kept in hiding was recovered and published after the war, and has become the most widely read document to emerge from the Holocaust.
Bieber's note read: "Truly inspiring to be able to come here. Anne was a great girl. Hopefully she would have been a Belieber."
Bieber's remarks led to criticism from some quarters, as a Facebook response insulting him received more than 1,000 "likes" - slightly more than the museum's original post about the incident.
Meanwhile on Twitter, posts mocking Bieber and imagining that he had visited the museum and walked away thinking only of himself began circulating, though the message is open to interpretation.
Some of Bieber's 37 million followers also tweeted messages of support. Others in his fan base - which is heavily weighted towards young girls - tweeted that they did not know who Anne Frank was.
Bieber's publicist and agent have not commented on the issue.
