WHO THE...?
In the following pictures, at least one Backstreet Boy is a PHONY.  They simply cannot be the Boy we know and love... so we have concluded they were temporarily replaced with "perfect" clones... or so they THOUGHT.
Meet "Brian."  Your first clue that this is not Brian, but actually "Brian", is his hideous outfit. 
Lora: OMG SAVE US ALL.  
Second clue... the hair??? and I mean just look at his face... NOT BRIAN.
Katie: Hammer pants. *dont touch this*
Introducing "Howie" and "Nick."
Lora: Was Howie's face ever that chubby?? and who the hell is this mini-nick thug?  and whats going on kevin's forehead?
Katie: What's up with Kevin's forehead?
Kevin??? Nah...
Katie:  Tonight on MTV, "Becoming" with the Backstreet Boys.  Four of the actual boys will be there, and then we will surprise one lucky fan with becoming Kevin.
Lora: But look at Brian!
Basically we just have no clue who the guy on the screen is.  He's just obviously not a Backstreet Boy, maybe a technician or something.
Katie:  Howie?
Lora: Kevin?
BACK TO DA WACK THANG
OH MY GOD... IMPERSONATORS... CLONES... IMPOSTERS... ITS NOT THEM!
