Britney Spears may have shot a video herself earlier this week, but now it's your turn. For her next Blackout single, "Piece of Me," the singer wants fans to give her a piece of them right back — by directing a separate video for her, with the winning clip to be played on TRL. The "Britney Spears Wants a Piece of You" contest launches on Monday, at which point MTV will open its vaults of the footage shot of the pop singer over the years, including interviews, red-carpet appearances and performances. Fans who want to get their Spielberg on can access the goods via the MTV Video Remixer. Pick the shots you like, mash them up and hit "send" — clips can be up to 3:34 in length or shorter. The grand prize winner also will receive a brand new Haier Ibiza Rhapsody device along with a one year subscription to Rhapsody, as well as the entire catalog of Spears' CDs and DVDs released in the U.S. Looking for inspiration or guidance to see how video mashes like these have been done in the past? Kelly Clarkson, Nelly Furtado, Common and Paramore have all given their fans chances to do Web-based video remixes on the site using Adobe Premiere Express, so watch their remixes first if you want to learn the technique, and then give Britney your best shot. MTV, Jive Records and Britney herself will decide the winner, whose video will be premiered exclusively on "TRL" on December 20. That's well before the airing of the video Spears shot this week — that won't surface until January at earliest. The winning "Piece of Me" video will also get an all-day premiere on MTV Hits and an online premiere on MTV.com.
