Depends in the UK there dedicated as *****
They buy anything with her name on it
Her album sell very well there
Battleship did well there
Her perfume is the fastest selling perfume there
11 dates at O2 Arena
and other records broken
While the US is less dedicated,she has alot more casual fans here they buy her stuff over time and not the day its release compared to some artist ex: Lady GaGa
I would give a overall 8
