Dying to get noticed by Britney Spears? Now's your chance with our "Get On Britney's Radar" contest sponsored by DanceJam.com! Simply upload a 30-60 video clip of you dancing to B's new hit single "Radar." Then starting this week, Britney and Jive Records will choose two finalists every week through Sept. 10. Submissions will be judged based on dance skill (40%), video popularity (20%) and overall appeal (40%). Each finalist will receive a copy of Britney's latest CD, Circus, and will be in the running to win the grand prize of Britney's entire music catalog (includes seven CDs and two DVDs.) The best part? YOU, the B fans, will vote for the grand-prize winner during the week of Sept. 10-17. Click here to view the dance vids, see what you're up against and rank your faves. Thinkin' about busting a move for Britney? A few tips from yours truly: 1) The earlier you enter, the better chance you have of becoming a finalist. Two finalists chosen every week through Sept. 10? You do the math. 2) Follow the Contest Rules. Want to submit a two-minute video? OK. But you won't get on B's Radar. 3) Dance your ass off and keep your moves sharp. 4) Opt for a fun outfit/costume. We like costumes. 5) Be creative. Good luck!
