Britney when she's surrounded by perverts -> shaves her head, end up on a gurney, etc..
Gaga when she's surrounded by perverts -> Gets Golden Globe awards, Oscar nominations, etc..
britney surrounded herself with users, not perverts, because she was in the midst of a mental breakdown and is in general pretty stupid
gaga surrounds herself with perverts because they're powerful and help her career because the public isn't fazed by their crimes (or weren't fazed when she had initially chose to work with them)
