No. all the guys from tokio hotel are single except Georg!March 28th 2010. Gustav's girlfriend had a baby! No one is sure of the girl's name yet.That was one of many untrue rumors.
when bill and tom started performing they were called black question mark but then when georg and Gustav joined they became devilish because of a review of them saying that they had devilishly great sound :)
In an interview, Bill Kaulitz said they all liked big cities--Tokyo, spelt Tokio in German, and they were always on the road, staying in hotels. I can't remember where it was but if you search youtube you'll probably find the interview. It was basically a summary of their journey.
