The lead singer from German Band Tokio Hotel. For most people who are wondering yes he is a guy and yes he is STRAIGHT!!!

This 20 year old singer is probably the hottest thing you can ever see. That is next to his twin brother Tom Kaulitz. Even though they are twins they have very different styles so it is very easy to tell them apart.

Some fans will just abbreviate his name with "BK" instead of typing it out.

And they will come up with cute saying like " BK- Bill Kaulitz! Have it your way"
Fan Girl #1: Whose your favorite member of TH?
Fan Girl #2: Bill Kaulitz!!! He is so adorable!!
Fan Girl #1: Yea he is but so is his brother.
Fan Girl #2: Yea they are probably the hottest twins ever!!

The sexy hexy guitarist for the German band Tokio Hotel that won the 2009 MTV EMA award for Best Group.

Famous for his attire, laidback attitude about sex (though he is now on the lookout for love), endless supply of sex jokes, and being ten minutes older than TH's vocalist, Bill Kaulitz. Some of Tom's other claims to fame include singing the harmony at the end of Monsoon (fifty seconds that has lead the TH fanbase to call it the Tom chorus), saying "sexy hexy" in one of the TH TV videos, humping his flying-V during concerts, and slapping one of the veiled TH stalkers while telling her to stay away from him, the band, and the Kaulitz family. He backup sings "raise your hands together” in the chorus of Raise Your Hands in both versions, along with Georg Listing.

Despite being a sex-obsessed playboy, Tom’s a pretty cool guitarist--though he doesn't know the first thing about reading music (he taught himself to pick out chords). His fanbase is made up of people who dream that they can change Tom from the luster that he identifies as, to a lover.

He has a lip ring, pierced ears, and wears baggy clothing. He used to have dreadlocks, but now has black cornrows. (Wanksta/wigger.)

TH's latest album Humanoid, has reminded fans that he's super-sexy hexy Tom Kaulitz. Thousands hope to be the one to change him. Change may be on Tom's current agenda, but fame and fortune are definitely at the forefront--he's a star, and he does what he wants.
Lexi: Tom. is. so. sexii hexii.
Razzle: Who?
Lexi: TOM KAULITZ! FROM TOKIO HOTEL.
Razzle: Please don't talk about him.
Lexi: BUT! WAH?! HE'S SOOOOOOOO HOT.
Razzle: Ew.

Singer from the band Tokio hotel (German band). He wears make-up,but it's hot. Born September 1, 1989. He is 10 minutes younger than his twin brother Tom Kaulitz. Neither of them have middle names. Bill is 6 ft. 2 inches. His favorite drink is peppermint tea(he says it is good for his voice). His favorite food is pasta. The first thing he notices about a girl is her hands. Also nice curves and a butt, she also has to be spontanious.

Bill Kaulitz is the hot lead singer from Tokio Hotel
He is so damn fine. his jawline is so sharp u could use it as a alternative for a knife. He's so fucking dreamy with his brown eyes like oh my god. He got me at a chokehold. I want to just kiss him all over. his voice is so damn- just- AHHH how tf can anyone be that perfect like he is the only attractive emo in the whole fucking world. His 2023 era is so damn fine too. some of my friends say he looks like a girl but at this point I don't really care what they think, they cant convince me he's ugly because he's not. sometimes, if my friends say anything bad about him I take it as a compliment because if I ever meet him, that means that they wont take him away from me. If anyone says anything bad about him their just jealous that they cant be as hot as him, like come on seriously. Some people are like "Ewwww Bill looks like a porcupine and tom looks like a mop! their both literally so ugly" FIRST OF ALL, Bill is not a porcupine and even if he was he would be MY porcupine and SECOND how actual fucking are u call tom a mop because of his dreadlocks. dreadlocks is apart of a culture and saying its ugly can disrespect some people and its quite racist in some ways too, AND tom isn't ugly.
Literally any Tokio Hotel fan: BILL KAULITZ IS SO TALENTED OMG
Hater: stfu no he's not, he's ugly af
Tokio Hotel fan: its kinda sad because u think I only care about his face and ur one to judge because u haven't even given his music a try yet so how about u stfu and mind ur own fucking business because i was never talking to u in the first place, self absorbed bitch
(WOW i got a little extreme there lmfao)
