Why am I a fan?
Well I think I'll have to start with the reason why Britney's still around; this girl is indestructible. She cannot be destroyed. And that's the reason why she's such a huge inspiration.
Just look online, or look in the news, or listen to the radio - people everywhere are making fun of Britney, posting photoshopped pictures of her or just making fun of her actions. Why? Because she's the person everybody loves to hate. Because maybe she hasn't made the best decisions at every turn. Because of the "everybody else makes fun of her and thinks it's funny so therefore if I do it it'll also be funny" mindset.
But does any of this stop Britney? Look at where she is now. She doesn't care what others think about what she does, and she doesn't let other people's opinions change who she is. Very few people have the ability to do that, and it's amazing how strong she is.
Haters can't even find anything about her that they can use to make fun of her with anymore. They can only make fun of the person who she used to be, but that's a pitiful and completely useless shot. Every single decision that Britney has recently made has been a good one, and she completely turned her life around.

She lost all that baby fat. How f***ing amazing is that? I couldn't believe my eyes when I saw those womanizer video pics that got leaked before the video was released. I was just like "Holy s***, is that really Britney?" And it was. And she's been working so freaking hard, and I have so much respect for her because of that. She's my motivation to work out and lose weight.

In fact, she's my motivation and inspiration for pretty much everything. So there's haters? Who the f*** cares - let them hate. It doesn't amount to anything.
And besides, how the hell could you not be a fan?
