When it comes to celebrities handling fame, there are those who handle it well and live normally as possible, then there are those who’re either destroyed by fame (especially if they’re highly self-destructive, contrary personality or suicidal) or if they use fame to get away with shady acts, even if it ironically brings more attention to it.
In the case with Britney Spears, she admits to being too shy for the music industry and possibly why she can’t handle it well, it’s like if you’re reserved and retiring you’re not much of a people person but when you’re made to please and entertain a lot of people there’s only so much emotional labour you can take until you snap, which’s probably her case.
(Spears might’ve done a lot of emotional labour to please and entertain people, even if it’s at the expense of her own preferences and personality like she wanted to do country music but made to sing contrary to her real voice.)
Then comes the second set of people who use their fame for shady ends, to get away with doing something bad without knowing that draws much more attention this way. As charismatic as David Bowie was, he also raped women and a teenaged girl even in the 1970s and 1980s as to show you he’s actually the kind of person to abuse his responsibility.
Some of the same things can be said of Michael Jackson and other celebrities who’ve slept with groupies, where they’re evidently the sort of character who’d abuse their power and responsibility to do really shady acts though this also overlaps with the former to some extent.
(Does bad things when famous, yet can’t handle fame that well either.)
Some people just don’t have the right personality for fame, let alone using it wisely that it takes a resolve to use fame for good and maybe enter another field where the pressure for celebrity’s minimised. Some abuse fame to do shady acts, others handle fame well enough.
