Because she just is. Whenever you hear the two words "Britney Spears", you know who is it about. You know it's the girl who danced in a school uniform, danced, created massive hits and ICONIC/MEMORABLE music videos, performed with a snake around her neck, kissed Madonna, discovered herself through her career/music, went through so many breakups, had her children taken away, had a meltdown, and yet, she is still back and better than ever.
