Britney Spears's OMG Moments

Her striptease! Her shocking videos! Her split from The X Factor and Jason Trawick! Look back at the star's biggest jaw-droppers

LETTING LOOSE

Spears drops Femme Fatale in March 2011, and lives up to its name in the cheeky music video for "I Wanna Go," in which she sends up her interactions with journalists, fans and paparazzi in a dream sequence about a pop star on the loose. Spears herself isn't safe from ridicule in the clip: She mocks her debut movie Crossroads – by performing in front of a marquee promoting the faux sequel Crossroads 2: Cross Harder.
