Justin Bieber spent another day on planet Earth yesterday, so inevitably something jaw-dropping ensued: It seems the Bieb decided to play tourist while in Amsterdam, and dropped by the Anne Frank House, entourage in tow and legions of screaming fans left bereft outside. Innocuous enough, even admirable. The kicker comes in the form of this statement from the museum, obtained by TMZ: "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.'"
