Bill and Tom Kaulitz (twins, born September 1, 1989), are popular German rock stars, best known for being in the band Tokio Hotel(formally known as Devilish). Bill sings the lead vocals and Tom plays the guitar. They are identical twins, although this is difficult to tell at first because of their different fashion styles. They have played shows together and starred in one movie. Since then, the brothers have continued to do music and endorsement deals together.

Early life
Born in Leipzig, Germany to Simone and Jörg Kaulitz, Tom was born 10 minutes before his brother Bill Kaulitz which makes Bill the younger brother. They were very hard to tell apart when they were younger so they had to wear t-shirts with their names written on it. Simone Kaulitz divorced Jörg when the twins were 7 seven years old and remarried Gordon Trümper which is where the boys get their surname Trümper, although they do not usually use it. They usually go by Kaulitz. Their stepfather, Trümper, had a major musical influence on the boys since he was in a band of his own at the time. This caused Bill to start writing his own songs and Tom to play an instrument of his choice. Over the years, the twins both dressed in skirt-suits until they reached their preteen years in which they started to develop their own sense of style and personality. During the years they were in school, they would always pull pranks on their teachers which led to their separation in later years in classes.

School Life
While attending school, Tom and Bill were not the popular type. It was said that before and after their fame erupted, they were called names such as faggot because of how they looked. They stated that they were just expressing themselves. Besides the name calling, Tom and Bill did well in school. Alledgelly, they both maintained a 1 or 2 which is exceptionally good in the German Grade (education). Even though they and the rest of the band did not finish high school because of their fame and schedules, they are completing online courses for school credit.

Personal life
Bill and Tom do not have any other siblings and it is unknown when their parents Simone and Jörg Kaulitz divorced or whether they still see him or not. The boys did remain under the care of their mother and Gordon Trümper after the divorce.

They both have had girlfriends in the past and their supposed ex-girlfriends spilled all in another popular German magazine, Popcorn Nr. 11, in which they tell what type of guys they are. Two girls that claimed to be Tom's ex-girlfriends were interviewed. The first stated that he was very unfaithful during their relationship which lead to their breakup and immediate relocation. The second one said that he was a very shy person during their relationship and they both didn't kiss until the 5th date. When asked about the rumors whether Tom has slept with 25 girls or not she responded: "He always makes from himself into a big macho man, but when it gets serious, he goes back. But he is a great guy." Another girl who was claimed by the German tabloids to be Tom's girlfriend was Ann-Katrin. She was known for dancing close with a very drunk Tom and kissing him on the cheek while being photographed. The next morning the pictures were seen in every tabloid. Tom tried to explain the pictures but it ended with death threats froms fans and hate around Europe directed to Ann-Katrin.

Style and Fashion
Though growing up dressing the same, the boys branched off into their own fashion sense when they hit their pre-teen stage. Bill, with his androgynous looks, could have a style referring to David Bowie with his fashion consisting of selected American band t-shirts, tight jeans, and punk style jewlery. He is also known for wearing thick eyeliner and exotic hair from manga to a lion style mane. He has two tattoos which consists of his band's logo, Tokio Hotel, on the nape of his neck and a star on his lower abdomen. Bill also has different taste in music. His music style consists of Nena, Green Day, and Keane.

Tom grew up with a more urban root to his style. Consisting of low sagging jeans, oversized shirts and jerseys, American caps and hats, headbands, and dreadlocks (a metre in length). Tom also has different taste in music from Bill. When he was younger, he listened to rock bands such as Aerosmith and AC/DC. He now expanded his taste to Hiphop and listens to such artists as Samy Deluxe and Snoop Dogg.
