Oh, dude, Tom Kaulitz totally has a middle name! It's Oliver. So, like, if you ever need to address him super formally, you can throw in that extra name and make him feel all fancy and stuff. But, like, let's be real, who actually uses their middle name unless they're in trouble with their mom?
Neither Bill or Tom have middle names and Bill and Tom Kaulitz are their full names.
They have no middle names so it's Bill Kaulitz and Tom Kaulitz.
@BILL_K and Tom's is @TOM_K
