Well, I know that there are some fans who still ask themselves if Bill Kaulitz has blonde hair. I will answer their question, hoping that they're going to be OK :)
Yes, Bill Kaulitz from TH has blonde hair, has muscles and beard. I can say that his change was made really fast and he has amaized all of us. He's not that guy who looked like a woman and who was beautiful in his own way anymore, now he keeps being beautiful in his way, but in a masculine way. We have to accept his change because it's his choise and this is the way he wants to be, he doesn't want to be a teenager anymore, he wants to be and to look like a man. I hope that you'll like the photos I'll post with him.
