In the short preview clip the 29-year-old pop queen stands on top of a taxi while surrounded by photographers.
Wearing cutesy pink socks, white leathers and a gingham bikini top publicity-shy Britney shows off her washboard stomach with gold belly button piercing.
In an act of media sabotage she swings her microphone around her head and floors two snappers with swift blows to the stomach. Sparks fly as the paps hit the street and Britney sings the lyrics 'I-I-I wanna go-o-o all the way-ay-ay taking out my freak tonight. I-I-I wanna show-o-o all the dir-ir-irt I got running through my mind...'
The song I Wanna Go is written by Max Martin, Shellback and Savan Kotecha. It is the third release from Britney's top-selling Femme Fatale album.
The raunchy music vid is directed by Chris Marrs Piliero for JIVE Records, a unit of Sony Music Entertainment.
The whole video will premiere on Wednesday, June 22.
On her Twitter site the Baby One More Time singer wrote: 'I-I-I wanna go-o-o all the way-ay-ay... but not quite yet... here's a peek at what's coming Wednesday tweeps.'
