Eastern European models with American names: why?

Why is it that Eastern European models either pick or are given American sounding names? 'Hana Montana' being the dumbest latest example that made me start this thread but it's obviously very common.
Personally I'd prefer they used names from their native countries instead. Obviously I know they won't be their real names but at least I can sort of make myself believe that they are. Hana Montana may just as well be called Daffy Duck for all the difference it would make in this regard!
