Exactly when and where has it ever been reported that Britney uses cocaine, much less has an addiction?
You just embarrassed yourself badly.
I suppose 'fans' like yourself will simply have to wait until she's trashed her career and in rehab to accept the reality of your 'hero'. Well, probably not even then.
Word of experience: people who compromise with evil become evil or become the victims of evil. Good thing you're 'Britney's fan'.
Since you're a D-head you'll just have to wait 2 years (my estimate) to see her 'Big performance' crashing and rehab.
