Justin Bieber has been making the rounds for his European tour. During his time in Amsterdam he visited an Anne Frank museum. Now, a comment he made about her is under some serious fire.

When Justin left the museum, he signed the guestbook. He said that the museum had been quite the inspiration and that he hoped that Anne would have been a 'belieber'.

It's not clear whether or not Justin was joking (hopefully he wasn't because that would be super low).

The museum posted the comment on their Facebook page and has been getting some truly negative responses.

Anne Frank was a huge fan of pop culture of her era, so it would make sense her for her to have liked Justin. We just hope he was serious.
