The show highlights Britney’s low points, like her head-shaving incident and attacking the paparazzi with an umbrella. Along with that, they also made fun of her 2007 MTV Video Music Awards performance of Gimme More that left many wondering what on earth happened to the legend that was Britney Spears.

Brit’s manager spoke to Access Hollywood about Glee’s tribute episode and said the singer was “livid” over the episode and they had no idea that the show was going to go down her troubled route.
