In her second-ever performance at the MTV Video Music Awards that September, Britney got everyone talking when she stripped off her black suit to reveal a sequined flesh-colored bodysuit underneath. "I'm Not a Girl, Not Yet a Woman" may have been a song on her next album, 2001's Britney, but the performance here proved that this girl was growing up. (And how quaint that this is what passed for controversial 20 years ago!)
