Many Anne Frank House visitors in Amsterdam disapprove of Justin Bieber's comments in the museum guest book that he hoped the young Holocaust victim would have been a "belieber," the popular term for his fans.

AMSTERDAM, THE NETHERLANDS (APRIL 15, 2013) (REUTERS) - Controversial comments made by popstar Justin Bieber that he hoped Anne Frank would have been a "belieber" -- the popular term for his fans -- were condemned as "inappropriate" on Monday (April 15) by some visitors to the Dutch museum dedicated to the young Holocaust victim.

"Truly inspiring to be able to come here. Anne was a great girl. Hopefully she would have been a belieber," his post said.

Some visitors on Monday commended his visit to the house, saying it showed another side to the singer.

"It proves that he doesn't just care about his concerts and his fans, he likes the history of the Netherlands and wherever he goes," teenager Lisa Jane Green said.

But in line with a large share of the hundreds of commentators on the museum's Facebook post who reacted negatively to Bieber's choice of words, other visitors criticised his note as "disrespectful".

"What was strange is what he wrote in Anne Frank's book, that Anne Frank would have hopefully been his believer, now I think that is a bit disrespectful," 15-year-old Bibi said.

"I read it in the news and I thought it was very inappropriate," Albanian tourist, 19-year-old Dalia said.

Anne Frank, who died at age 15 at the Bergen-Belsen concentration camp in 1945, is one of the most well-known and celebrated Jewish victims of the Holocaust.

Readers around the world have read her diary, which was first published in 1947 and details the deprivations and personal triumphs she and her family experienced in hiding during the Nazi occupation of the Netherlands.

Some commentators on social media sites commended Bieber for caring enough about Anne Frank's story to visit the Amsterdam museum, which is built into the house where she and her family hid before their arrest.

And the museum itself did not criticise the Canadian-born star in its post.

Annemarie Bekker, a spokeswoman for the Anne Frank House, said museum officials were "a bit overwhelmed" by the negative reaction to Bieber's statement.
