Justin Bieber needs a lesson on history and humility, online commenters have deduced. After stopping by the Anne Frank House in Amsterdam on Friday, the 19-year-old pop star has caused outrage for claiming that the Jewish history legend would have been a "belieber" had she survived today.

The Facebook page of Anne Frank House posted on Saturday:

"Yesterday night Justin Bieber visited the Anne Frank House, together with his friends and guards. Fans were waiting outside to see a glimpse of him. He stayed more than an hour in the museum. In our guestbook he wrote: 'Truly inspiring to be able to come here. Anne was a great girl. Hopefully she would have been a belieber.' Tonight Bieber will give a concert in Arnhem in the Netherlands."

A belieber is what a fan of the Canadian singer is called. His followers are normally in the "tween" (from 8 to 12 years old) and teen age groups.

Anne Frank, a victim of the Holocaust, was 15 when she died in 1945. Her diary, which chronicled her life from 1942 to 1944 as she hid with her family from the Nazis in the upper rooms of her father's office in Amsterdam, had been published in 1952 to universal acclaim.

The outrageous statement was deemed too self-serving by Internet commenters, with some calling Bieber an immature boy who is full of himself.

One comment on the Anne Frank House page reads: "No, Anne wouldn't have been a Belieber. She wouldn't have had his picture on her wall because she had much better taste than that."

"Beyond disappointing that Bieber totally missed the point," said another one.

Actress Emmy Rossum also weighed in on the issue, posting on her Twitter: "Anne Frank suffered WW2 and Justin Bieber hopes she would have been a fan? I have no words."

Maatje Mostart, spokeswoman for the Anne Frank House, meanwhile defended the pop star, telling ABC News that the museum didn't find his remarks offensive.
