1. When she officially became our definitive sex symbol with just a chair and a crop top.
The only woman to ever make 'The Pleasure Principle' look tame.
2. Those bomb abs she debuted on the 'Dream Within a Dream Tour.'
Because what pre-pubescent teenage boy cared about the anatomy of a girl's waistline before this HBO special? (Also, not forgetting this was the greatest pop tour of our time.)
3. When she became the OG T-Swift by creating her greatest album (In The Zone) after an intensely public breakup.

Thanks JT for giving us the most sonically cohesive pop album, pre-1989. You the real MVP here!
4. That red jumpsuit featured in the "Oops!... I Did It Again" music video.
Yeah. We're in love.
5. This once-controversial cover.

... which was on every 90s kid's bedroom ceiling.
6. The fact that she featured Pharrell, Snoop Dogg, and the Ying Yang Twins on her records before it was even mainstream to do so. (Officially giving her street cred)

But forreal Brit, can we get that unreleased 'Outrageous' video?
7. Everything about this Showtime special.
Sneaking to watch 'The Onyx Hotel Tour' was well-worth every parental punishment received for staying up late.
8. When she dated the "quarterback" of the music industry that we all wanted to be...

And needed the cornrows and studded bandana for our transformation to be complete.
9. When she revealed to Rosie O'Donnell that she was smart as hell and got a 1450 on the SAT's in the seventh grade.

Officially becoming the intellectual girl of our dreams.
10. Every impromptu spill we made on an airplane because of this music video.
Oh... So that's what that does?
11. When she covered our favorite classic songs, thus having something further to talk about with our girlfriends.
Who knew The Rolling Stones' 'Satisfaction' would one day become a televised strip tease in a nude body suit?
12. Everything about this video.

She was such a lovable goofball.
13. And of course, the entire Toxic music video...
Enough said.
