The Army never warms to ppl who make their fave look unimpressive (Gaga, Taylor, Adele, Bey), so they use whoever is left as a shield, hopping from one to another. Kesha 2010-2012; Katy 2012-present. They haven't used Britney's receipts since at least the ITZ era. From 2007-onward, it's just been "iconic! wow! her breakdown was totez legendary! princess of pawp!"
