Britney Spears is not a huge fan of the paparazzi. She took them down in her “Pieces of Me” video and in her new video for “I Wanna Go”, the pop star turns the table on the paparazzi again by fighting them with her microphone. In a newly released teaser video clip, a fit and smiling Spears is shown seeking ninja-like vengeance against the paparazzi and their prying lenses. She’s standing atop a taxi while cameramen surround her from all angles. Wielding a microphone, the singer whips it around like a weapon knocking the paparazzi from their positions. Spears, who kicked off her Femme Fatale tour last week does not show any dance moves in her latest video but she does get frisked by an attractive police officer and promotes a fake movie “Crossroads 2: Cross Harder”, a nod to her 2002 movie “Crossroads”.
