Controversial comments made by popstar Justin Bieber that he hoped Anne Frank would have been a "belieber", were condemned as "inappropriate" on Monday (April 15) by some visitors to the Dutch museum dedicated to the young Holocaust victim.

The Anne Frank House Facebook page reported on Saturday that the young star had made the comments in its guest book, news which provoked some hostile reactions on social media.

"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".

"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.

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.
