In Class 7, at school, Bill was separated from his twin brother Tom, because they played too many tricks and pranks. Long before that, in primary school, they already threw paper balls and ink at their teachers.

• Bill has a grade average of 1,9, which is really good in Germany. It's also higher than Tom's: 2,2 (in Germany, 5 is the lowest grade, while 1 is the highest).

• Bill was only seven when he started writing lyrics. He writes most of Tokio Hotel's songs, and his texts are considered to be quite mature for his age.

• He is ten minutes younger than Tom.

• He often has the same dreams as his brother.

• They have the same best friend, Andreas.

• In kindergarten, they had shirts with their names on them so people could tell them apart. Over the years they have started to look slightly different, though.

• Tom and Bill both got their first kiss from the same girl when they were ten, though Bill got it one day later.

• Bill participated in Star Search (2003), singing Geri Halliwell's "It's Raining Men".

• Despite the comments he often gets due to his exotic appearance, Bill is not gay.

• When Bill and Tom both like the same girl, they let her choose.

• He is single; according to him, "unfortunately...". Contrary to his brother Tom, he looks for something steady in girls. Looks don't matter too much to him ("There are so many sweet girls!"): as long as a girl is witty, spontaneous and has a powerful look to her eyes (and preferentially doesn't bite her nails), everything's good.

• He would never take girls with him (i.e., for sex) after a concert.

• Though Tom has admitted to have had more sex than him, Bill never made it clear whether he's still a virgin or not. "Maybe I'm still waiting for that certain someone, who knows...". Girls, take your own conclusions.

• He will flirt, but only with body language.

• According to himself, his tongue piercing isn't a problem when it comes to kissing. I'd still like to try that out, just to make sure.

• Bill is totally unsporty.

• He does not smoke.

• He is sensitive, and worries a lot.

• According to himself, he can't dance; instead, he's the type of person to stand in a corner watching while others do (not literally, I hope).

• Bill and his brother would love to meet the Olsen twins.

• His biggest dream is to play in Tokyo once.

• He'd like to go shopping in New York.

• He has nothing against groupies. "I mean, who does dislike them?"

• Bill was twelve when he got his eyebrow piercing, and thirteen when he got the tongue one: both allowed by his parents. However, the tattoo on the back of his neck with the Tokio Hotel logo was made secretly, when he was fifteen.

• His parents are very liberal, and allowed him to go to parties at a young age.

• Bill enjoys discussions (in a good way) and will gladly have one. He talks a lot; not as much as his twin brother, though.

• He still does his make-up the same way he did when he once attended a cetain party as a vampire.

• Bill wanted to be a witch when he was younger.

• He spends one or two hours doing his hair everyday.

• He uses Dove deodorant.

• Bill is extremely artistic and draws and designs clothes a lot. When he's done in the music business, he expects to become a fashion designer.

• His favorite food is pizza and fast-food noodles. He won't eat what he doesn't know.

• He's allergic to mosquito repellents.

• Bill uses one can of hairspray a week.

• He gets the most fanmail in Tokio Hotel: around fifty letters a day (go figure).

• When they were six, he and Tom played in a movie called "Verrόckt Nach Dir".

• Their mother is called Simone.

• He got a PSP for his sixteenth birthday, and owns an iBook (like an iPod).

• He has a filter for unknown numbers on his cellphone.

• He gets €50 every month from his parents, but spends it all near the beginning of the month; contrary to Tom, he's bad at spending money consciously.

• Bill sings everywhere, and says about himself that "he can be vain".

• He wears boxer-briefs.
