I don't like things like this even if it is for my gurl Britney but let's not act like people don't do these things for Gaga, Beyonce and others...mainly those two. It's just called stanning unnecessarily.
"success" is varying though depending on the person. I wouldn't call someone who's sold a lot of albums, but now seems drugged and unhappy to be all that successful. I love Britney to death, and I feel like she would rather stop doing music and just be a mom.
