He is no longer the cuddly youthful Bill Kaulitz you knew..
At the age of 21, Bill has perfectly grown into a man with a deeper handsome voice for him to speak out and sing, while carrying a more matured look compared to the old days of Tokio Hotel where he had the lion-mane hair until the era of his sexy mohawk slowly fades away with time. The mohawk was chopped off, leading the daring Bill Kaulitz to do a new hairdo with a more fashion-wise approach, giving him a total look of an alluring rockstar model that seemingly to suit him well as he is the one and only around ;) It is also to be said as an Elvis Presley inspired cut. Such an old school for a 21st century alien boy, wait i mean, Man, young Man! ;)
A demure and divine young man how Bill has turned into, now. Yeah, so maybe Bill is still young at heart but of course, he's growing older and wiser each day. By looking at his unique gorgeous structured face at present, you can tell that lines of wrinkles will appear sooner than you knew it and he'll never be that golden shinning boy you admire and be charmed by. Instead, he'll be that one man you would desire to make him as your beloved partner in the future and so as a father to your children. Only time will tell for that. Okay, maybe I'm over exaggerating, he's only 21 for God's sake! ;p But I believe someday, Bill Kaulitz will come to a term that he needs to wake up and see the world from a Man's perspective view in life, for a change ;) He'll be a maturely adult, eventually as he can't own a youthful age forever now.
" In the end, You're just a camouflage of an immortal-like human, Bill ;) "
