Bill Kaulitz was known as the most mysterious person in Rock & Roll. Nobody knew anything about him more than his name, age and that he was a singer.

Lately, there have been rumors around that he had a girlfriend. Or a sex slave. All sources said a different thing.

After half an hour of knocking, Bill finally opened up the door.

"What."
