THE SNAKE AT THE MTV VIDEO MUSIC AWARDS (2001) Performing “I’m a Slave 4 U,” Spears emerged from a cage with a white tiger by her side, then moved to the back of the stage a few minutes later to continue performing with a live python draped around her neck.

THE KISS AT THE MTV VIDEO MUSIC AWARDS (2003) While performing “Hollywood” with Madonna, Missy Elliott and Aguilera, Spears (and we viewers) were shocked when Madge leaned over and proceeded to plant a big, fat, wet one on her lips.

THE REALITY SHOW (2005) “Britney and Kevin: Chaotic,” a critically savaged five-episode UPN show, chronicled her and then-hubby Kevin Federline’s relationship from their courtship, engagement and wedding.

THE ON-AIR MELTDOWN (2006) Matt Lauer interviewed Spears on “Dateline NBC” during a particularly stressful period of her life. “I’m an emotional wreck right now,” she said, tearing up. “I’m not perfect. I’m human.”
